ide: add struct ide_port_ops (take 2)
* Move hooks for port/host specific methods from ide_hwif_t to
'struct ide_port_ops'.
* Add 'const struct ide_port_ops *port_ops' to 'struct ide_port_info'
and ide_hwif_t.
* Update host drivers and core code accordingly.
While at it:
* Rename ata66_*() cable detect functions to *_cable_detect() to match
the standard naming. (Suggested by Sergei Shtylyov)
v2:
* Fix build for bast-ide. (Noticed by Andrew Morton)
