[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.
