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.
