mtd: Remove mtd_erase_callback() entirely
The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).
All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.
Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

mtd: mtdpart: Make mtdpart's _erase method sane
The _erase() method of the mtdpart driver, part_erase(), currently
implements offset shifting (for given mtdpart partition) in a weird way:
1. part_erase() adds partition offset to block address
2. parent driver's _erase() method is called
3. parent driver's _erase() method calls mtd_erase_callback()
4. mtd_erase_callback() subtracts partition offset from block address
so that the callback function is given correct address
The problem here is that if the parent's driver does not call
mtd_erase_callback() in some scenario (this was recently a case for
spi_nor_erase(), which did not call mtd_erase_callback() at all), the
offset is not shifted back.
Moreover the code would be more readable if part_erase() not only added
partition offset before calling parent's _erase(), but also subtracted
it back afterwards. Currently the mtd_erase_callback() is expected to do
this subtracting since it does have to do it anyway.
Add the more steps to this procedure:
5. mtd_erase_callback() adds partition offset to block address so that
it returns the the erase_info structure members as it received them
6. part_erase() subtracts partition offset from block address
This makes the code more logical and also prevents errors in case
parent's driver does not call mtd_erase_callback() for some reason.
(BTW, the purpose of mtd_erase_callback() in Linux is to inform the
caller that it is done, since in Linux erasing is done asynchronously.
We are abusing the purpose of mtd_erase_callback() in U-Boot for
completely different purpose. The callback function itself has empty
implementation in all cases in U-Boot.)

clk: sifive: Fix -Wint-to-pointer-cast warning
dev_read_addr() returns a value of type fdt_addr_t which is a 64-bit
address and pd->va is a pointer. In a 32-bit build, this causes the

board: sifive: Fix a potential build warning in board_fdt_blob_setup()
Commit 47d73ba4f4a4 ("board: sifive: overwrite board_fdt_blob_setup in u-boot proper")
added a board-specific implementation of board_fdt_blob_setup() which
takes a pointer as the return value, but it does not return anything
if CONFIG_OF_SEPARATE is not enabled. This will cause a build warning
seen when testing booting S-mode U-Boot directly from QEMU, per the
instructions in [1]:
board/sifive/unleashed/unleashed.c: In function ‘board_fdt_blob_setup’:
board/sifive/unleashed/unleashed.c:125:1: warning: control reaches end of non-void function [-Wreturn-type]

clk: fixed_rate: add dummy disable() function
commit 6bf6d81c1112 ("clk: fixed_rate: add dummy enable() function")
implemented .enable, so fixed rate clocks can be used where drivers
might call clk_enable(). Implement the .disable op for the same reason;
some drivers, e.g. USB PHYs, may attempt to disable clocks at runtime.

tools: Stop re-defining -std= when building tools
While we intentionally set -std=gnu11 for building host tools, and have
for quite some time, we never dropped -std=gnu99 from tools/Makefile.
This resulted in passing -std=gnu11 ... -std=gnu99 when building, and
gnu99 would win. This in turn would result now in warnings such as:
tools/mkeficapsule.c:25:15: warning: redefinition of typedef 'u32' is a C11 feature [-Wtypedef-redefinition]
typedef __u32 u32;

This enables the clock controller driver support on TI's SoCs. This will
fix this GPIO issue at boot time:
request_and_set_gpio: Unable to request GPIO_PR1_MII_CTRL
request_and_set_gpio: Unable to request GPIO_MUX_MII_CTRL
request_and_set_gpio: Unable to request GPIO_FET_SWITCH_CTRL
request_and_set_gpio: Unable to request GPIO_PHY_RESET
This issue comes from the fact that the clock controller is not probed.
Enable the TI's clock controller driver support to solve this.

Makefile: Only build dtc if needed
At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined, even
when DTC is provided. The built dtc is not actually used, so this is a
waste of time.
Update the Makefile logic to build dtc only if one is not provided to the
build with the DTC variable. Add documentation to explain this.
This saves about 3.5 seconds of elapsed time on a clean build of
sandbox_spl for me.
