Series ata: optimize core code size on PATA only setups | expand

Commit Message

Bartlomiej Zolnierkiewicz March 26, 2020, 3:57 p.m. UTC 
There is no reason to expose SATA_PMP config option when no SATA
host drivers are enabled. To fix it add SATA_HOST config option,
make all SATA host drivers select it and finally make SATA_PMP
config options depend on it.

This also serves as preparation for the future changes which
optimize libata core code size on PATA only setups.
