sata_promise: cleanups
This patch applies some trivial cleanups to sata_promise: - repair whitespace damage - correct comment at board_2057x_pata definition - pull SATAII TX4 support code out to separate functions - rename ata_nr to ata_no for consistency with libata's port_no - remove some init-time debug printks (requested by Jeff) This patch should cause no behavioural changes, except for the removed printks.
