[PATCH v3 3/3] gpio: rda: Use bidirectional GPIO register for direction input

[Dang Huynh]

The current implementation uses both DIRIN and DIROUT registers, but
the bgpio library expects 1 to be output direction, which on this IP
is reversed (0 = output, 1 = input).

To fix this, use GPIO_OEN_VAL for input direction register which
expects 1 = input, 0 = output.

This change should not affect any mainline users as none of them have
any peripherals hooked up to a GPIO.
