[PATCH 4/9] drm: atmel-hlcdc: Define SAM9X7 XLCDC specific registers

[Manikandan Muralidharan <manikandan.m@microchip.com>]

From: Durai Manickam KR <durai.manickamkr@microchip.com>

The register address of the XLCDC IP used in SAM9X7 are different from
the previous HLCDC.Defining those address space with valid macros.
