AM35x supports only 32bit read operations so we need to have
workaround for 8bit and 16bit read operations.

AM35x is based on OMAP35x but has an updated musb interface which
uses CPPI4.1 DMA engine.
Current patch supports only PIO mode transfers.

Changes from v1: (Based on Sergei's comment)
- Moved PHY clock and OTGMODE settings to board
Currently DMA channels are allocated and they remain allocated
even if there is no active data transfer. Added channel_release()
whenever there is no pending request.

Removed unneeded 'power' and 'mode' field from musb_config as
they are now getting updated by the values provided from board
files at usb_musb_init().
