gpio: mpc8xxx: Rename Kconfig option, structures, and functions

Browse source 
Rename the Kconfig option, structures (and their members), as well as
functions of the mpc85xx driver to include mpc8xxx to reflect the more
generic usage.

Aside from the standard functions of input/output mode, and output
value setting, the open-drain feature, which can configure individual
GPIOs to work as open-drain outputs, is supported.
The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.
