soc/intel/apollolake: Use fixed resource for SRAM and IPC1

Browse Source 
Intel telemetry support will require PMC IPC1 and SRAM devices to be
operated in ACPI mode. Then using fixed resources on BAR0, BAR1
and BAR2 (PMC only) for those two devices will help
the resource assignment in DSDT stage.

BUG=chrome-os-partner:57364
BRANCH=None
TEST=Boot up into Chrome OS successfully and check with dmesg to see
the driver has been loaded successfully without errors.
