This adds support for the TI nspire panels to the simple panel roster. This code is based on arch/arm/mach-nspire/clcd.c. This includes likely the first grayscale panel supported.
These panels will be used with the PL11x DRM driver.

You can now add my: Reviewed-by: Sam Ravnborg sam@ravnborg.org
I assume this will be applied as one series and you will do it when ready.

ChangeLog v1->v2:
- Bump clock frequency to 10 MHz after Fabian's trial-and-error
- Changed vsymbol names to ti_nspire_*
- Sorted alphabetically
- Specify positive edge on the classic display bus
