ARM: OMAP: Remove unused platform devices, v3

This patch removes old platform devices. Alsa should now
be using the ASoC driver. For boards not yet using ASoC,
please see sound/soc/omap/osk5912.c.

Add dummy aic23_power_up and aic23_power_down functions for 770
to keep things compiling.

Remove references to omap_gpio_switch, and unused h2_nand_dev_ready
function.

This patch is based on an earlier patch by Arun KS.
