Input: adp5589-keys - fix adp5589_gpio_get_value()

The adp5589 seems to have the same behavior as similar devices as
explained in commit 910a9f56 ("Input: adp5588-keys - get value from
data out when dir is out").

Basically, when the gpio is set as output we need to get the value from
ADP5589_GPO_DATA_OUT_A register instead of ADP5589_GPI_STATUS_A.
