ide: remove IDE_ARCH_LOCK (v2)
* 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.
v2:
* Build fix from Geert updating ide_{get,release}_lock() callers in
falconide.c.
