ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms 



Add compulsory device tree support to the Cirrus ep93xx ARMv4 platform.

- select PINCTRL_EP93xx
- select COMMON_CLK_EP93XX, as clock driver moved out of platform code
- select ARCH_HAS_RESET_CONTROLLER

Select ARM_ATAG_DTB_COMPAT to update device tree with information
about memory passed from bootloader.

We have to leave all MACH options as they are used for board checking
before decomp, to turn off watchdog and ethernet DMA.
