regulator (max5970): Fix IRQ handler
The max5970 datasheet gives the impression that IRQ status bits must
be cleared by writing a one to set bits, as those are marked with 'R/C',
however tests showed that a zero must be written.
Fixes an IRQ storm as the interrupt handler actually clears the IRQ
status bits.
