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.
