drivers/intel/fsp2_0: Simplify FSP global reset definition

According to all FSP 2.x specifications, the OEM status code have the
highest bit clear and the next to highest bit set. Therefore, the FSP
reset status varies with the FSP architecture.

This commits reduces the global reset Kconfig to a single one
specifying the suffix X of
`FSP_STATUS_RESET_REQUIRED_X'. `fsp_reset.c' constructs the name of
the constant by macro expansion and concatenation to determine which
`FSP_STATUS_RESET_REQUIRED_X' constant to map to the global reset
request.

Compared to the previous implementation:

- It is scalable (the number of Kconfig should not evolve with FSP
  specification addition new OEM status code).

- It does not introduce any duplicate and prevent wrong values C
  header files and Kconfig.

- It use the FSP (or other) header files coreboot is compiled against
  for `FSP_STATUS_RESET_REQUIRED_X' constants

- It works with both 32-bit and 64-bit FSP binaries

Since all the platforms defining
SOC_INTEL_COMMON_FSP_RESET (tigerlake, alderlake, jasperlake,
meteorlake, pantherlake, elkhartlake, skylake, cannonlake and
apollolake) pick a global reset value, this commit default the most
common: 3.

As a result of using the appropriate constants and because FSP 2.x
status code varies with the FSP architecture, this commit includes
some necessary changes to a few function prototypes manipulating FSP
status codes.
