This patch adds wrappers to dwc3_omap_readl/writel calls to accomodate
both OMAP5 and AM437x reg maps (It uses the cached register offsets).
Also renames OMAP5 IRQ1 as IRQMISC and IRQ1 bits as IRQMISC bits.

This patch Initializes the register offset values depending
on the X_MAJOR of USBOTGSS_REVISION register. Also adds register
offset defines and new debug register defines.
X_MAJOR is 2 for both OMAP5 and AM437x. But both have different
glue register layout. Differentiate AM437x using dt compatible.
Register offsets are cached in dwc3_omap struct for reg reads
and writes.

AM437x and OMAP5 dwc3 subsytem have different register map.
Major differences are as follows.
OMAP5 has one main interrupt and one misc interrupt
Aegis has four main interrupts and one misc interrupt.
Miscellanous Interrupt offsets are changed.
UTMI OTG Control and Status Registers offsets are changed.
DEBUG Configuration and Status Registers are changed.
The main intend of the patch is to re-use the same wrapper driver
for both OMAP5 and AM437x, by using the x_major in revision
register and adjusting the offsets.
This patch adds the register map offsets and adds offset variables
in struct dwc3_omap to cache the offsets
