IA32 build from VS2019 toolchain has security violation
because Digest value from SHA512_384 is not matching the
value calculated and stored in hashstore during build.
Aligning the stack to 32-byte boundary during SHA_Update
fixes this error.

In 32 bit SBL, when PCI PMEM64 exists, the OsLoader will hang

This patch tries to standardize the PreOS support.
The PreOS could be TrustyOS, PreOsChecker or others.
As long as PreOS flag is set in boot option, SBL will load and
boot PreOS before normal OS. If the preOS has specific requirement,
it could be addressed using PreOS image type.

BGRT can be used by bootloader to pass logo to OS. But BGRT can
only support 24bit or 32bit BMP format. If the bootloader uses
other bit format or indexed color format, the image has to be
converted before passing it to BGRT. This patch added support
to convert other BMP image format into 32bit format required by
BGRT.
This has been tested with Windows on Leafhill board. The SBL
logo was dispalyed properly while booting Windows.
