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 Change-Id: Id8be986185282521aee574027503eaf8968e1508 Signed-off-by: Jett Rink <jettrink@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/31682 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
