[PATCH] PCI: imx6: Use gpio_set_value_cansleep()

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

We are in a context where we can sleep, and the PCIe reset gpio may be
on an I2C expander.  Use the cansleep() variant when setting the GPIO
value.

Based on a patch from Russell King for pci-mvebu.c.
