[PATCH 105/133] [Jaunty SRU] ARM.imx51 Freescale:ENGR00112477 SDHC: Remove GPIO pin inactive/active on suspend/resume

[Brad Figg]

From: Xiexiaobo <X.Xie at freescale.com>

The MX25-3DS used a GPIO pin as detect_irq, when system suspend,
mxc_free_gpio() will disable this GPIO irq, but the mxc_request_gpio()
don't enable this GPIO irq, so the insertting and removing SD/MMC
can not be detected after suspend and resume operations. This fixed it.
