soc/intel/common/dmi: Add DMI driver support

This change allows configuring the General Purpose
Memory Range(GPMR) register in BIOS to set up the decoding in DMI.

This driver provides the following functionality:
1. Add a helper function dmi_enable_gpmr which takes as input base,
limit and destination ID to configure in general purpose memory range
registers and then set the GPMR registers in the next available
free GMPR and enable the decoding.
2. Add helper function get_available_gpmr which returns available free
GPMR.
3. This helper function can be utilized by the fast SPI driver to
configure the window for the extended BIOS region.
