driver/intel/ish: add ish chip driver support
We want to be able to specify the firmware variant suffix
in the devicetree.cb configuration for particular firmware
builds. This driver allows us to specify the firmware_variant
property in the device tree and have it populate a _DST table
in the SSDT ACPI table for the ISH device, thus making the
suffix available to the kernel (See crrev.com/c/1433482 for kernel
change that uses the value)
BUG=b:122722008
TEST=decompile DDST table and verify that new firmware-variant value
is present. Also verfied that kernel can access this new field using
the shim loader kernel CLs
