4ce022d396 x86: fsp: Move struct fspinit_rtbuf definition to chipset header
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.

81f84aa6c9 x86: fsp: Rename update_fsp_upd() and change its signature
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.

cb379a34c4 x86: fsp: Rename shared_data to fsp_config_data
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.

f0285fbe4e x86: fsp: Avoid cast stack_top in struct shared_data
Declare stack_top as u32 in struct shared_data and struct common_buf
so that we can avoid casting in fsp_init().

aa02446406 x86: fsp: Simplify fsp_continue()
There is no need to pass shared_data to fsp_continue() so we can
remove unnecessary codes that simplifies the function a lot.

412400abaa x86: Split out fsp_init_phase_pci() code into a new function
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.

82196cf34f x86: Adjust the FSP types slightly
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.
