gpio/rockchip: fix get_direction value handling
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.
