pdc202xx_old: always enable burst mode
Alan has noticed that distros always enabled burst mode
(+ datasheet confirms that it is the right thing to do).
Thus fix pdc202xx_old host driver to do it unconditionally
and remove no longer needed CONFIG_PDC202XX_BURST option.

- This option causes the pdc202xx driver to enable UDMA modes on the
- PDC202xx even when the PDC202xx BIOS has not done so.

- It was originally designed for the PDC20246/Ultra33, whose BIOS will
- only setup UDMA on the first two PDC20246 cards. It has also been
- used successfully on a PDC20265/Ultra100, allowing use of UDMA modes
- when the PDC20265 BIOS has been disabled (for faster boot up).
