Kconfig: Create RAMPAYLOAD kconfig
This patch enables coreboot flow to skip ramstage as individual stage to load payload. Instead it is expected to load payload from postcar stage.

+ help
+ If this option is enabled, coreboot flow will skip ramstage
+ loading and execution of ramstage to load payload.
+
+ Instead it is expected to load payload from postcar stage itself.
+
+ In this flow coreboot will perform basic x86 initialization
+ (DRAM resource allocation), MTRR programming,
+ Skip PCI enumeration logic and only allocate BAR for fixed devices
+ (bootable devices, TPM over GSPI).
