Subject: [PATCH RESEND v9 1/8] drm: atmel-hlcdc: add driver ops to differentiate HLCDC and XLCDC IP

Add LCD IP specific ops in driver data to differentiate
HLCDC and XLCDC code within the atmel-hlcdc driver files.
XLCDC in SAM9X7 has different sets of registers and additional
configuration bits when compared to previous HLCDC IP. Read/write
operation on the controller register and functionality is now
separated using the LCD IP specific ops.
