gpio: max730x: make pullups configurable via platformdata
The gpios on the max730x chips have support for internal pullups while in input mode. This patch adds support for configuring these pullups via platform data. A new member ("input_pullup_active") to the platform data struct is introduced. A set bit in this variable activates the pullups while the respective port is in input mode. This is a compatible enhancement since unset bits lead to disables pullups which was the default in the original driver. _Note_: the 4 lowest bits in "input_pullup_active" are unused because the first 4 ports of the controller are not used, too.
