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).
