regulator: irq: freeze deferred hardware access during suspend
The regulator IRQ helper delays status checks and recovery callbacks on
non-freezable workqueues. Those callbacks may access regulator hardware
after the backing bus has been suspended.
Use system_freezable_wq for normal-priority callbacks. Allocate a
freezable high-priority workqueue when requested so the high_prio
contract is preserved while hardware access is frozen across suspend.
