ARM: imx: merge plat-mxc into mach-imx
It's really unnecessary to have plat-mxc, and let's merge it into mach-imx. It's pretty much just a bunch of file renaming and Kconfig/Makefile merge. To make the change less invasive, we keep using Kconfig symbol CONFIG_ARCH_MXC for mach-imx sub-architecture.
