Subject: [PATCH v6 1/6] platform/x86: intel_pmc_ipc: fix gcr offset

According to Broxton APL PMC spec, gcr mem region starts
at offset 0x1000 from ipc mem base address. In this driver,
PLAT_RESOURCE_GCR_OFFSET macro defines the offset of GCR
memory region from IPC mem region. So we should use 0x1000(4K)
as GCR offset. But currently this driver uses 0x1008 as GCT
offset.This patch fixes this issue.
