mmc: sunxi: Fix misuse of gpio_direction_input()
It does not make sense to make gpio_direction_input() return the gpio input
status. The return value of gpio_direction_input() is inconsistent if
CONFIG_DM_GPIO is defined.
And we don't need to call gpio_direction_input() int sunxi_mmc_getcd().
Just init the gpio once in mmc_resource_init() is enough.
