[U-Boot] [PATCH 1/2] dm: gpio: mxc: fix mxc_gpio_bank_get_value

When configured a gpio to output direction, directly reading PSR register can not return the output value, since we did not set SION bit for gpio iomux. So, we can use data register to reflect what value is outputed. If not, "regulator status" always return disabled, even if already "regulator
