[PATCH v2 1/2] ARM: mxs: detect SoC by checking CHIPID register

[Marek Vasut]

> 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.
