x86: fsp: Support a warning message when DRAM init is slow
With DDR4, Intel SOCs take quite a long time to init their memory. During
this time, if the user is watching, it looks like SPL has hung. Add a
message in this case.
This works by adding a return code to fspm_update_config() that indicates
whether MRC data was found and a new property to the device tree.
Also add one more debug message while starting.

x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUME
At present this enables a few arch-specific members of the global_data
struct which are otherwise not part of the struct. As a result we have to
use #ifdef in various places.
The cost of always having these in the struct is small. Adjust things so
that we can use compile-time code instead of #ifdefs.

timer: Allow delays with a 32-bit microsecond timer
The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

ARM: da850-evm: Unify config options with Kconfig
There are two options that are currently whitelisted, but they
are redundant, because there are not necessary since Kconfig options
exist to basically state the same thing.
CONFIG_DIRECT_NOR_BOOT and CONFIG_USE_NOR are both set together and
only used by the da850 when booting from NOR, however the only time
CONFIG_MTD_NOR_FLASH is configured is when booting from NOR. Since
NOR doesn't need SPL, the options for SPL can be moved to a check for
building SPL instead of checking for NOR.
This patch removes the checks for these two config options and unifies
the checks around the Kconfig option of CONFIG_MTD_NOR_FLASH.
Since this board is the only board that uses these two config options,
they can be removed from the whitelist table.

README: davinci: Clarify when SPL is used and the target devices.
The documentation states that SPL is enabled in all config options
for the da850. This incorrect, because devices booting from NOR
do not need the SPL to do the low level initializion because when
booting from NOR, the board is able to execute in place (XIP)
This also clarifies that SPL isn't only used for booting from SPI,
because it is also used for booting from MMC and NAND for those
devices supporting those boot options.
