msm: cpr-regulator: Improve CPR interrupt handling
disable_irq() is not an efficient call and could cause potential deadlock.
Improve the interrupt handling by removing disable_irq and enable_irq
completely, and instead, checking the state of the interrupt source
(LOOP_EN and BUSY bits) in ISR to bail out immediately if any condition is
not met.
