x86: Fix linking u-boot with ld.lld
When linking the final u-boot binary with LLD, the following link errors
are seen:
ld.lld: error: can't create dynamic relocation R_386_32 against local
symbol in readonly segment; recompile object files with
-fPIC or pass '-Wl,-z,notext' to allow text relocations

According to Nick Desaulniers:
"This is a known difference between GNU and LLVM linkers; the GNU
linkers permit relocations in readonly segments (making them not read
only), LLVM does not (by default)."
Since U-Boot apparently seems to use relocations in readonly segments,
change the global linker flags to permit them when linking with LLD by
specifying '-z notext'.

include: axp_pmic: Include headers for all variants
A single DM-based driver should be able to support some feature for
several PMIC variants where the interface is the same. For example,
all PMIC variants use the same register bit to trigger poweroff.
However, currently only definitions for a single PMIC are available at
a time. This requires drivers to use #ifdefs and different indentifiers
for each variant they support.
Let's simplify this by making register definitions for all variants
available from the header. Then no preprocessor conditions are needed;
the driver can use the register definition from any variant that
supports the relevant feature.
An exception is the GPIO-related definitions, which do not use unique
identifiers. So for now, keep them like before. They will be cleaned up
along with the GPIO driver.

This header attempted to avoid multiple inclusion using a header guard.
But the preprocessor symbol was never defined, so the guard had no
effect. Fix this by defining the symbol.

sunxi: A23/A33/H3: Actually move the secure monitor
commit 1ebfc0c631e3 ("sunxi: A23/A33/H3: Move sun8i secure monitor to
SRAM A2") attempted to move the secure monitor to SRAM A2. But not all
sun8i SoCs have SRAM A2, so a check was put in for SUNXI_SRAM_A2_SIZE to
avoid breaking the other SoCs.
However, because the header providing SUNXI_SRAM_A2_SIZE was not
included, this unintentionally skipped the new definitions on all SoCs.
Fix this by including the right header.

phy: sun4i-usb: Support VBUS detection via power supply
The device tree binding provides for getting VBUS state from a device
referenced by phandle, as an optional alternative to using a GPIO. In
U-Boot, where there is no power supply class, this VBUS detection will
be implemented using a regulator device and its get_enable method.
Let's hook this up to the PHY driver.

phy: sun4i-usb: Refactor VBUS detection to match Linux
The Linux driver checks the VBUS detection GPIO first; then VBUS power
supply; then finally assumes VBUS is present. When adding VBUS power
supply support, we want to match that order, so we get the same behavior
in case both a GPIO and a power supply are provided in the device tree.
So refactor the function a bit to remove the early return, and use the
same "assume VBUS is present" final fallback.

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.
