In this driver, PLAT_RESOURCE_GCR_OFFSET macro defines the offset of GCR region base address from IPC base address and its current value of 0x1008 is incorrect because it points to location for PMC_CFG register and not the GCR base address itself. GCR Base = IPC1 Base + 0x1000. This patch fixes this offset issue.
