Robert Jarzmik 9f296fe271 ARM: dts: pxa: add pincontrol helpers
Add 3 helpers so that pincontrol definitions for pxa25x and pxa27x are
easier, and can be easily converted from old mfp mach-pxa code to
devicetree.

An example of such conversion would be :
static unsigned long mioa701_pin_config[] = {
	GPIO32_MMC_CLK,
	GPIO92_MMC_DAT_0,
	GPIO109_MMC_DAT_1,
	GPIO110_MMC_DAT_2,
	GPIO111_MMC_DAT_3,
	GPIO112_MMC_CMD,
	MIO_CFG_IN(GPIO78_SDIO_RO, AF0),
	MIO_CFG_IN(GPIO15_SDIO_INSERT, AF0),
	MIO_CFG_OUT(GPIO91_SDIO_EN, AF0, DRIVE_LOW),
};
into:
	pinctrl_mmc_default: mmc-default {
		PMMUX(sd-insert, 15, gpio_in);
		PMMUX(mmclk, 32, MMCLK);
		PMMUX(sd-ro, 78, gpio_in);
		PMMUX_LPM_LOW(sd-enable, 91, gpio_out);
		PMMUX(mmdat0, 92, MMDAT<0>);
		PMMUX(mmdat1, 109, MMDAT<1>);
		PMMUX(mmdat2, 110, MMDAT<2>);
		PMMUX(mmdat3, 111, MMDAT<3>);
		PMMUX(mmcmd, 112, MMCMD);
	};

The third column of PMMUX*() helpers can be found in pincontrol muxing
functions, either in pinctrl-pxa27x.c (or pinctrl-pxa25x.c), or by
inspecting the pincontrol once booted in debugfs.
