Both imx23 and imx28 have CHIPID register at address 0x8001c310, which can be used to identify the SoC. This patch changes cpu_is_xxx and __arch_decomp_setup to use this CHIPID register than machine type to detect the chip between imx23 and imx28, so that we do not need to change these functions whenever a new board/machine gets added.
