Subject: [PATCH] ide: remove IDE_ARCH_LOCK
* Add ->{get,release}_lock methods to struct ide_port_info
and struct ide_host.
* Convert core IDE code, m68k IDE code and falconide support to use
->{get,release}_lock methods instead of ide_{get,release}_lock().
* Remove IDE_ARCH_LOCK.

We may also consider adding struct ide_host_ops later...
