sata_promise: separate SATA and PATA ops
This patch changes sata_promise so that the PATA ports
on TX2plus chips are bound to the pdc_pata_ops structure.
This means that operations called from the SATA ops
structures don't need any SATA-vs-PATA tests any more.
Instead, operations that depend on a port being SATA or
PATA are separated into different procedures.
* pdc_cable_type() is split into a PATA version and a
SATA version
* pdc_error_handler() is split into a PATA version and a
SATA version, that both call a common version after
setting up the `hardreset' function pointer
* pdc_old_check_atapi_dma() is now only used for SATAI
ports, so is renamed to pdc_old_sata_check_atapi_dma()
and simplified
* pdc_sata_scr_{read,write}() are now only used for SATA
ports, so their is-not-SATA tests are removed
* pdc_port_start() is split into three procedures: a wrapper
which performs the ->ops adjustment on TX2plus PATA ports,
a procedure with the common code, and a procedure with
the SATA-specific code (this bit might be cleaned up by
Tejun's new init model)
Tested on 20619, 20575, and 20775 chips.
