Subject: [PATCH libata #promise-sata-pata] sata_promise: 2037x PATAPI support

This patch adds ATAPI support for the PATA port on Promise 2037x chips.
It depends on the common sata_promise ATAPI support patch.

First-generation chips don't support ATAPI on their SATA ports, so
the patch removes ATA_FLAG_NO_ATAPI from the 2037x common host flags,
and adds it back via the _port_flags[] entries for the SATA ports.
