[ARM] 4737/1: Refactor corgi_lcd to improve readability + bugfix
This patch refactors the code in corgi_lcd.c moving it to the board specific corgi and spitz files where appropriate instead of the existing ifdef mess which hinders readability. Fix spitz_get_hsync_len() to call get_hsync_invperiod so pxafb can be compiled as a module. The confusing variables which represent the inverse horizintal sync period are renamed to "invperiod" consistently. An incorrect comment in corgi_ts.c is also corrected.
