Subject: ARM: pxa: stargate2: use device properties for at24 eeprom

We want to work towards phasing out the at24_platform_data structure.
There are few users and its contents can be represented using generic
device properties. Using device properties only will allow us to
significantly simplify the at24 configuration code.

Remove the at24_platform_data structure and replace it with an array
of property entries. Drop the byte_len/size property, as the model name
already implies the EEPROM's size.

Subject: ARM: pxa3xx: enable external wakeup pins

The PXA3xx SoCs feature dedicated pins for wakeup functionality. These pins
have no alternate functions, so let's always enable them as wakeup source on
DT enabled boards. The WAKEUP1 pin is only available on PXA320.
