Frederic Weisbecker 627f364d24 locking/lockdep: Use expanded masks on find_usage_*() functions ...

In order to optimize check_irq_usage() and factorize all the IRQ usage
validations we'll need to be able to check multiple lock usage bits at
once. Prepare the low level usage mask check functions for that purpose.
