arm-soc: board specific changes

These updates are all for board specific code, including

* defconfig updates for shmobile, davinci, bcm2835, imx, omap and tegra
* SD/MMC and I2C support on bcm2835 (Raspberry PI)
* minor updates for PXA
* shmobile updates to GPIO usage in board files
* More things in OMAP board files are moved over to device tree probing
* Better support for audio devices on some OMAP platforms

Conflicts include the omap board-apollon.c file that is removed without
a replacement, and conflicting context in the 4430sdp board file.
