system76-coreboot/src/soc/intel/alderlake/Kconfig
Subrata Banik a00db94270 soc/intel/{adl, cmn}: Allow config to select the OCP workaround 
This patch introduces a config option for SoC code to choose
the applicable SoC workaround.

For now, we have introduced `SOC_INTEL_UFS_OCP_TIMER_DISABLE`
to apply UFS OCP timeout disable workaround.

At present ADL SoC only selects so, and in future MTL and others
should check with Intel prior selecting this kconfig.

It's the placeholder to add more workaround in required going forward.

BUG=none
TEST=Able to build and boot Google/Brya.
