ARCv2: Enable LOCKDEP
- The asm helpers for calling into irq tracer were missing
- Add calls to above helpers in low level assembly entry code for ARCv2
- irq_save() uses CLRI to disable interrupts and returns the prev interrupt
state (in STATUS32) in a specific encoding (and not the raw value of
STATUS32). This is usable with SETI in irq_restore(). However
save_flags() reads the raw value of STATUS32 which doesn't pair with
irq_save/restore() and thus needs fixing.
