[PATCH] Revert "pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'"

[haibo.chen@nxp.com]

From: Haibo Chen <haibo.chen@nxp.com>

This patch block system booting, find on imx7d-sdb board.
From the dts we can see, iomux and iomux_lpsr share the memory region
[0x30330000-0x3033ffff], so will trigger the following issue:

[    0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver
[    0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff]
[    0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16

This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9.
