This series adds driver model support to the GPIO and serial drivers used
by Raspberry Pi, and moves Raspberry Pi over to driver model.
This requires adding driver model support to the pl01x serial driver, and
replacing the bcm2835 GPIO driver with a driver model version (since there
are no longer clients that don't use driver model).
See u-boot-dm.git branch rpi-working for the tree this is based on.
Changes in v3:
- Add new patch to add missing private data size for serial_pl01x
Changes in v2:
- Adjust header file include to dm/platform_data/...

Adjust the configuration to use the driver model version of the pl01x
serial driver. Add the required platform data.

The private data size is missing from the driver, so we store it at 0,
which causes problems when something overwrites memory at 0.
Fix this.
