Intel: Remove CACHE_MRC_BIN - 'selected' everywhere in Kconfig

The Kconfig symbol CACHE_MRC_BIN was getting forced enabled everywhere
it existed.

Remove the Kconfig symbol and get rid of the #if statements
surrounding the code.

This fixes the Kconfig warning for Haswell & Broadwell chips:
warning: (NORTHBRIDGE_INTEL_HASWELL &&
NORTHBRIDGE_INTEL_SANDYBRIDGE &&
NORTHBRIDGE_INTEL_SANDYBRIDGE_NATIVE &&
NORTHBRIDGE_INTEL_IVYBRIDGE &&
NORTHBRIDGE_INTEL_IVYBRIDGE_NATIVE &&
CPU_SPECIFIC_OPTIONS) selects CACHE_MRC_BIN
which has unmet direct dependencies
(CPU_INTEL_SOCKET_RPGA988B || CPU_INTEL_SOCKET_RPGA989)
