    Subject[PATCH 35/43] ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms
    Date
    This adds compulsory device tree support to the Cirrus ep93xx ARMv4
    platform.

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

    And also we need 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.

    Notes:
    rfc->v0
    - fixed typo
    - removed board-dt.c completely
