ARM: add versatile family consolidated CLCD support This consolidates the CLCD panel definitions and memory allocation into one location. Rename the Sanyo 2.5in and Epson 2.2in displays after their respective part numbers. Rather than using a general "Sanyo 2.5in" and "Epson 2.2in" description of the display panel, use the manufacturers part number to be more specific. This helps people identify what the timings actually refer to, which are panel specific. While here, add CLCD capability information to each panel definition, which has no effect until we add the board-level capabilities.

video: fix up versatile CLCD helper move commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers") moved files out of the plat-versatile directory but in the process got a few of the dependencies wrong: - If CONFIG_FB is not set, the file no longer gets built, resulting in a link error - If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a Kconfig warning for incorrect dependencies due to the symbol being 'select'ed from the platform Kconfig. - When the file is not built, we also get a link error for missing symbols. This patch should fix all three, by removing the 'select' statements, changing the Kconfig description of the symbol to be enabled in exactly the right configurations, and adding inline stub functions for the case when the framebuffer driver is disabled.
