This patch prevents from the situation where we may end up with garbage
displayed on the LCD panel.
Such situation occurs when one performs "reboot -f" in Linux and then
stop in U-boot (or observe the garbage on the screen during boot up).
To prevent from such situation - the PWM pin is configured as GPIO and set
to LOW.

According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit
is set to 1 before the caches and MMU are enabled, or any cache and TLB
maintenance operations are performed".
ROM sets this bit in normal boot flow, but when in serial download mode,
it is not set.
Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms,
including mx7d, mx6ul/ull and mx7ulp.

If GPT gets broken, then after N boot attempts we will run the SWUpdate
restoration image.
On its enter we will check GPT and restore it if needed.
To test it:

Test case:
The fitImage gets corrupted:
truncate -c -s 3M fitImage
run tftp_mmc_fitImg

[board shall hang in SPL with
"Trying to boot from MMC1" information]
Then after X seconds WDT is causing board to reset. After N boot attempts
we enter recovery mode.

To enter the special mode, one needs to short cut two pads with e.g. screw
driver.
After power up the SPL will execute u-boot in which proper actions will be
taken.
It is worth noting that we do not alter envs (even the BOOT_FROM variable)
and unconditionally go to recovery.

At present the EFI application and payload support codes in the x86
directory is distributed in a hybrid way. For example, the Kconfig
options for both app and payload are in arch/x86/lib/efi/Kconfig,
but the source codes in the same directory get built only for
CONFIG_EFI_STUB.
This refactors the codes by consolidating all the EFI support codes
into arch/x86/cpu/efi, just like other x86 targets.

UEFI specifies the calling convention used in Microsoft compilers;
first arguments of a function are passed in (%rcx, %rdx, %r8, %r9).
All other compilers use System V ABI by default, passing first integer
arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9).
These ABI also specify different sets of registers that must be preserved
across function calls (callee-saved).
GCC allows using the Microsoft calling convention by adding the ms_abi
attribute to a function declaration.
Current EFI implementation in U-Boot specifies EFIAPI for efi_main()
in the test apps but uses default calling convention in lib/efi.
Save efi_main() arguments in the startup code on x86_64;
use EFI calling convention for _relocate() on x86_64;
consistently use EFI calling convention for efi_main() everywhere.
