Subject: [PATCH v2 0/9] Add support for XLCDC to sam9x7 SoC family.

This patch series aims to add support for XLCDC IP of sam9x7 SoC family
to the DRM subsystem.XLCDC IP has additional registers and new
configuration bits compared to the existing register set of HLCDC IP.
The new compatible string "microchip,sam9x75-xlcdc" is defined for sam9x75
variant of the sam9x7 SoC family.The is_xlcdc flag under driver data helps
to differentiate the XLCDC and existing HLCDC code within the same driver.

changes in v2:
* Change the driver compatible name from "microchip,sam9x7-xlcdc" to
"microchip,sam9x75-xlcdc".
* Move is_xlcdc flag to driver data.
* Remove unsed Macro definitions.
* Add co-developed-bys tags
* Replace regmap_read() with regmap_read_poll_timeout() call
* Split code into two helpers for code readablitity.
