[U-Boot] [PATCH V2 0/6] Add support for SPI based DataImage LCD panel

[Nikita Kiryanov]

This patch ports the Linux driver for DataImage SCF0403852GGU04 and
SCF0403526GGU20 LCD panels into U-Boot. As a preparation step, variable SPI word
length support is added to omap3_spi and the generic SPI interface.
Finally, the driver is used in cm_t35 board.

The SPI changes were tested with a Beagle I2C/SPI/MDIO Protocol Analyzer, and
also with a DataImage SCF0403 lcd as part of the DataImage driver test.

Patch number 6 depends on http://patchwork.ozlabs.org/patch/275283/

Changes in V2:
	- Rebased on top of latest U-Boot
	- New patches:
		 1) spi: omap3: remove semicolon from #define
		 2) spi: define SPI_XFER_ONCE
		 3) omap3_dss: define DSS_ONOFF
	1 is a preliminary cleanup suggested by Gerhard Sittig and Igor Grinberg
	2 and 3 are splitting off some new #defines to separate patches
	- Moved wordlen to generic spi_slave struct, and added generic
	implementation for spi_set_wordlen which only updates the struct without
	touching the hardware (Igor Grinberg)
	- Updated wordlen in hardware just before doing SPI transactions, not
	when changing wordlen (Igor Grinberg)
	- OMAP3 specific check of wordlen value from old implementation of
	spi_set_wordlen moved to xfer. It refines the more general check done
	in the new spi_set_wordlen.
	- Fixed comment style in spi.h following a rebase on top of latest
	U-Boot
	- Added SPDX-License-Identifier to all new files (Anatolij Gustschin)
	- s/printf/puts for not formatted strings in scf0403 driver (Anatolij
	Gustschin)
	- Do not fail scf0403 driver init if an invalid reset_gpio is given
	(Igor Grinberg)
