Add support for the Okaya RS800480T-7X0GP to the DRM simple panel driver.
The RS800480T-7X0GP is a WVGA (800x480) panel with an 18-bit parallel LCD interface. It supports pixel clocks in the range of 30-40 MHz.
This panel details can be found at: http://boundarydevices.com/product/7-800x480-display/
