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.
