soc/intel/elkhartlake: Make hard drive type for SATA ports configurable

Intel's EHL FSP offers the possibility to select the connected hard
drive type to SATA ports. One has the option to choose between HDD ('0'
- default) and SSD ('1').

This patch provides a chip config so that this FSP parameter can be set
as needed in the devicetree on mainboard level.
