pinctrl: pxa: pxa2xx: add pin configuration support
Add pin configuration for pxa2xx architectures. PXA doesn't provide any
bias, push, pull capabilities. The only capability is to set a state for
the pins when the platform enter sleep or deep sleep mode.
The state of a pin is set by :
- whether the GPIO direction was input or output
- if it is output, a register set programs whether the pin should be
held to ground or VccIO
