FSP spec 1.1 adds one more member to the struct common_buf to
determine the memory size that can be reserved by FSP below "top
of low usable memory" for bootloader usage. This new member uses
the reserved space so that it is still compatible with previous
FSP spec 1.0.
A new HOB (FSP_HOB_RESOURCE_OWNER_BOOTLOADER_TOLUM_GUID) is also
published when common_buf.tolum_size is valid and non zero.

All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf
as defined by the 1.0 spec, however there are FSPs that does not
follow 1.0 spec (possible due to that FSP predates the 1.0 spec),
and future FSP binary that is complaint to v1.1 spec defines an
optional paltform-specific runtime data in the struct fspinit_rtbuf.
Hence move the definition to chipset header.

To support platform-specific configurations (might not always be
UPD on some platform), use a better name update_fsp_configs() and
accepct struct fsp_config_data as its parameter so that platform
codes can handle whatever configuration data for that FSP.

FSP has several config data like UPD, HDA verb table which can be
overridden or provided by bootloader. Currently in U-Boot only UPD
is handled via struct shared_data. To accommodate any platform, we
rename shared_data to fsp_config_data and move the definition from
common place fsp_support.h to platform-specific place fsp_configs.h.

This code may be useful for boards that use driver model for PCI.
Note: It would be better to have driver model automatically call this
function somehow. However for now it is probably safer to have it under
board control.

When running as an EFI application, U-Boot must request memory from EFI,
and provide access to the boot services U-Boot needs.
Add library code to perform these tasks. This includes efi_main() which is
the entry point from EFI. U-Boot is built as a shared library.

To avoid casts, find_fsp_header() should return a pointer. Add asmlinkage
to two API functions which use that convention. UPD_TERMINATOR is common
so move it into a common file.
