ide: replace the global ide_lock spinlock by per-hwgroup spinlocks (v2)
Now that (almost) all host drivers have been fixed not to abuse ide_lock
and core code usage of ide_lock has been sanitized we may safely replace
ide_lock by per-hwgroup locks.
This patch is partially based on earlier patch from Ravikiran G Thirumalai.
While at it:
- don't use deprecated HWIF() and HWGROUP() macros
- update locking documentation in ide.h
v2:
Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns)
