regmap: Merge up fixes
The main thing here is a fix for lockdep warnings with MMIO regmaps that
use a raw spinlock and a cache, some other lockdep fixes we'd done for
the benefit of the maple tree on sleeping buses meant that we were doing
allocations for those MMIO regmaps under a raw spinlock. While fixing
that Michael Reeves also noticed that the debugfs files were briefly
available without the cache structures backing them.
There's also a fix for interrupt freeing on error in regmap-irq which
had been hanging around because it's not super urgent.
