Merge "usb: usb_bam: Add generic support for host mode"

- qti,descriptor-fifo-offset: descriptor fifo offset address

Optional properties :

- qti,bam-mode: BAM mode can be one of.

	0 - BAM_MODE_DEVICE

	1 - BAM_MODE_HOST

	(If not set will be set by default to BAM_MODE_DEVICE)

- qti,ignore-core-reset-ack: If present then BAM ignores ACK from USB core

	    while performing PIPE RESET

- qti,disable-clk-gating: If present then disable BAM clock gating.
