soc/intel/apl: Fix programming temporary MTRR on GLK
Programming MTRR happens later in the CONFIG_SOC_INTEL_COMMON_BLOCK_CPU_MPINIT codepath. fast_spi_cache_bios_region() assumes an existing MTRR solution from x86_setup_mtrrs_with_detect(). This fixes a problem introduced by 829e8e6 "soc/intel: Use common codeflow for MP init".
