[PATCH] rivafb: kill riva_chip_info and riva_chips

Kill riva_chips_info and riva_chips and replace the NV_ARCH_ determination
with a less error prone one.  We better use the driver_data for something
more interesting later.

From: "Antonino A. Daplas" <adaplas@hotpop.com>

  1. modified patch so it's in -p1 form
  2. killed compile warning when CONFIG_FB_RIVA_I2C is not set
  3. changed U032 to u32 in riva_get_arch()
