ARM: imx: move iomux drivers and headers into mach-imx
The board files in mach-imx are the only users of iomux drivers and headers. Move them into mach-imx from plat-mxc. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de>

-/*
- * build IOMUX_PAD structure
- *
- * This iomux scheme is based around pads, which are the physical balls
- * on the processor.
- *
- * - Each pad has a pad control register (IOMUXC_SW_PAD_CTRL_x) which controls
- * things like driving strength and pullup/pulldown.
- * - Each pad can have but not necessarily does have an output routing register
- * (IOMUXC_SW_MUX_CTL_PAD_x).
- * - Each pad can have but not necessarily does have an input routing register
- * (IOMUXC_x_SELECT_INPUT)
- *
- * The three register sets do not have a fixed offset to each other,
- * hence we order this table by pad control registers (which all pads
- * have) and put the optional i/o routing registers into additional
- * fields.
- *
- * The naming convention for the pad modes is MX35_PAD_<padname>__<padmode>
- * If <padname> or <padmode> refers to a GPIO, it is named
- * GPIO_<unit>_<num>
- *
- * IOMUX/PAD Bit field definitions
- *
- * MUX_CTRL_OFS: 0..11 (12)
- * PAD_CTRL_OFS: 12..23 (12)
- * SEL_INPUT_OFS: 24..35 (12)
- * MUX_MODE + SION: 36..40 (5)
- * PAD_CTRL + NO_PAD_CTRL: 41..57 (17)
- * SEL_INP: 58..61 (4)
- * reserved: 63 (1)
