Subject: [PATCH] Samsung LMS283GF05 LCD SPI support

This patch adds support for the SPI part of LMS283GF05 LCD. The LCD uses SPI for initialization and powerdown sequences. No further defails are specified in the datasheet about the initialization/powerdown sequence, just the magic numbers that have to be sent over SPI bus. This LCD can be found in the Aeronix Zipit Z2 handheld.
