Improve atyfb_atari_probe():
* Call correct_chipset() so that more par members, par->features in
  particular, get initialized.
* If probe fails iounmap() the mapped regions and continue probing for more
  adapters.

Only verified to cross-compile due to lack of hardware.

This patch adds a way to create and use the video plane (YUV overlay) and
scaling video scaling features of the chip.

The overlay is configured, resized and modified using a device specific
ioctl.

Also included in this patch:
  - If no platform data was passed, print an error and exit instead of crashing.
  - Added a write_reg(_dly) macro. This improves readability when
    manipulating chip registers. (no more udelay() after each write).
  - Comments about some issues.

The LCD type is choosen by a new field in the s3c2410fb_mach_info structure
and its value is the value of the PNRMODE bits.  This worth to be noted as
a value of 0 means that you configure a 4 bit dual scan stn display.
