[PATCH] gpio: adnp: Fix testing wrong value in adnp_gpio_direction_input

[Axel Lin <axel.lin@xxxxxxxxxx>]

Current code test wrong value so it does not verify if the written
data is correctly read back. Fix it.

BTW, I'm wondering why it needs to read back the written vlaue for double
checking if write is success or not.
Without any comment, it looks like a leftover of testing code.
Does it make sense to remove the read after write?
