soc/intel/sgx: convert SGX and PRMRR devicetree options to Kconfig
The devicetree is not made for user-choosable options, thus introduce
Kconfig options for both SGX and the corresponding PRMRR size.
The PRMRR size Kconfig has been implemented as a maximum value. At
runtime the final PRMRR size gets selected by checking the supported
values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest
to the chosen one.
When "Maximum" is chosen, the highest possibly value from the MSR gets
used. When a too strict limit is set, coreboot will die, printing an
error message.
