SPI controllers can easily implement MIPI DBI mode C, with the help of GPIO pins for the reset and command/data signals. Introduce a MIPI DBI compliant SPI driver, which emulates MIPI DBI mode C (SPI 3 and 4 wire). Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>

Enable support for MIPI DBI SPI driver. This driver implements

a MIPI-DBI mode C compatible controller using a SPI device, as well

as GPIO outputs for the reset and D/C signals

Support 3 wire MIPI DBI (Mode C option 2) in MIPI DBI SPI
|

driver. This requires manually packing each byte with a data/command
|

bit, and may slow down display data transmission.
