regulator: ltc3676: Fix incorrect IRQSTAT bit offsets

The LTC3676_IRQSTAT_* bit definitions do not match the IRQSTAT
(Interrupt Request Status) register layout documented in Table 15
of the LTC3676/LTC3676-1 datasheet:

  bit 0 - Pushbutton Status Active
  bit 1 - Hard Reset Occurred
  bit 2 - PGOOD Timeout Occurred
  bit 3 - Undervoltage Warning
  bit 4 - Undervoltage Standby (Fault) Occurred
  bit 5 - Overtemperature Warning
  bit 6 - Overtemperature Standby (Fault) Occurred
  bit 7 - Reserved

The driver instead defines these starting at bit 3, one bit higher
than the datasheet specifies, which causes ltc3676_regulator_isr()
to check the wrong status bits and misreport (or miss) PGOOD
timeout, undervoltage and thermal warning/fault conditions.

Fix the bit offsets to match the datasheet.
