gpio/rockchip: fix get_direction value handlinggpio-fixes-for-v5.15-rc3
The function uses the newly introduced rockchip_gpio_readl_bit() which directly returns the actual value of the requeste bit. So using the existing bit-wise check for the bit inside the value will always return 0. Fix this by dropping the bit manipulation on the result.
