d362a08817 x86: Reduce resetvec size
At present this produces a 16-byte file. It is intended to start 16 bytes
before the end of ROM and pads with zeroes to readh the end.

But binman sometimes wants to add an image-header at the very end of ROM.
Furthermore binman automatically pads the data if it is finishes early.

Drop the padding in resetvec and let binman handle it.

add3f4c918 x86: Add a function to set variable MTRRs
Normally U-Boot handles MTRRs through an add/commit process which
overwrites all MTRRs. But in very early boot it is not desirable to clear
the existing MTRRs since they may be in use and it can cause a hang.

Add a new mtrr_set_next_var() function which sets up the next available
MTRR to the required region.

6172e94c3c x86: Change condition for using CAR
At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off
blocks) are not, since HOBs typically indicate that an FSP is in use, and
FSPs handle the CAR init.

However this is a bit indirect, and for FSP2 machines which use their own
CAR implementation (such as apollolake) but use the FSP for other
functions, the logic is wrong.

To fix this, add a dedicated Kconfig option to indicate when CAR is used.

This slimbootloader CPU type is to enable U-Boot as a payload which
runs on top of Slim Bootloader (https://github.com/slimbootloader).
The Slim Bootloader is designed with multi-stage architecture for
the execution from reset vector to OS booting, and supports QEMU,
Apollolake, Whiskeylake and Coffeelake platforms consuming Intel
FSP (https://github.com/IntelFsp) for silicon initialization
including CAR and memory initialization.
The Slim Bootloader generates new HOB (Hand Off Block) which are
serial port info, memory map info, performance data info and so on,
and passes it to a Payload. U-Boot as a payload will use these HOB
information for basic initialization such as serial console.

As an initial commit,
- Add CONFIG_SYS_SLIMBOOTLOADER to enable slimbootloader CPU type
- Add new arch/x86/cpu/slimbootloader directory with minimum codes
- Get hob_list pointer from Slim Bootloader
