tridentfb: replace macros with functions
This patch replaces macros with static functions and puts tridentfb_par pointer as the first argument of these functions. These is a step toward multihead support. Additionally, bogus TRIDENT_MMIO define is removed as the driver supports graphics cards only through the mmio mode. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Cc: "Antonino A.
