video/macfb: Remove redundant code
The value of info->var.bits_per_pixel get checked in macfb_setcolreg(). Remove additional checks as they are redundant. macfb_defined.activate gets initialized to FB_ACTIVATE_NOW by the struct initializer. Remove redundant assignments. macfb_defined.bits_per_pixel, .width and .height all get assigned unconditionally. Remove redundant initializers.
