[PATCH 1/3] ARM: imx6: introduce CONFIG_SOC_IMX6 for i.MX6 common stuff

[Shawn Guo]

The i.MX6 SoCs have something in common, so let's introduce
CONFIG_SOC_IMX6 for those stuff.

[PATCH 2/3] ARM: imx6: rename pm-imx6q.c to pm-imx6.c

[Shawn Guo]

The pm-imx6q.c works for all i.MX6 SoCs, so let's rename it to pm-imx6.c
and have the build controlled by option CONFIG_SOC_IMX6.

[PATCH 3/3] ARM: imx6: build suspend-imx6.o with CONFIG_SOC_IMX6

[Shawn Guo]

Even when CONFIG_SUSPEND is enabled, it makes no sense to build
suspend-imx6.o if none of i.MX6 support is built in.  Let's build
suspend-imx6.o only when both CONFIG_SUSPEND and CONFIG_SOC_IMX6 are
enabled.
