usb: msm_otg: Support LPAE systems

Targets having large physical address extension support
enabled (CONFIG_ARM_LPAE) have phys_addr_t and dma_addr_t
defined as 64-bit types. When printing messages with these
addresses the format string needs to use '%pa' instead of
'%x' and pass the physical address by reference. This patch
addresses these in the USB 2.0 OTG, host, and gadget controller
drivers.

Also extend coherent dma_mask from 32-bits to 64-bits to match
that of dma_mask.  This fixes the following runtime error when
booting on LPAE systems:

	msm_hsusb msm_hsusb: coherent DMA mask 0xffffffff is smaller
	than system GFP_DMA mask 0xffffffffffffffff
