This patch updates the sata_promise driver to use new-style
libata error handling for 20619 (TX4000) chips. sata_promise
already uses new EH for the other chips it supports, so the
patch is quite simple:
* remove ->phy_reset and ->eng_timeout ops from pdc_pata_ops,
and instead bind ->freeze, ->thaw, ->error_handler, and
->post_internal_cmd to existing new EH functions
* drop ATA_FLAG_SRST from board_20619's flags
* remove now unused pdc_pata_phy_reset() and pdc_eng_timeout()
* pdc_pata_cbl_detect() is now unused, but it contains a cable
detection procedure that I don't think is mentioned in public
documentation, so for now I just wrapped it with #if 0/#endif
Tested on a TX4000 with both modern working disks and old/quirky
disks. Also used a CD-RW drive to test reading and writing CDs.

The lack of cable detection definitely sounds like a bug...?
The standard procedure is to set ap->cbl in your 'prereset' EH hook, as
is done in drivers/ata/pata_sil680.c.
