* [PATCH 1/2] input: adp5588-keys - get value from data out when dir out

As discussed here: http://ez.analog.com/message/35852,
the 5587 revC and 5588 revB spec sheets contain a mistake
in the GPIO_DAT_STATx register description.

According to R.Shnell at ADI, as well as my own
observations, it should read:
"GPIO data status (shows GPIO state when read for inputs)".

This commit changes the get value function accordingly.

A similar patch for gpio-adp5588 follows.
