plat: imx7: refactor code for reuse
For the iMX7 SOCs, part of the code for platform setup implementation can be reused and made common for all these SoCs. This patch extracts the common part for reuse. Signed-off-by: Jun Nie <jun.nie@linaro.org> Change-Id: I42fd4167e6903416df96a0159a046abf3896e878
