[PATCH RESEND v9 2/8] drm: atmel-hlcdc: Define XLCDC specific registers

[Manikandan Muralidharan]

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

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