[PATCH 3/4] power: supply: bq25630: Add macro define for IRQ cycle time

[Waqar Hameed <waqar.hameed@axis.com>]

The interrupt pulse time of 256 µs can be seen as an "inherent" property
of the device. It is currently only used for when polling the reset
register, but it could/should be used when polling whatever
register (e.g. liquid check). To facilitate this, add a macro define for
the interrupt pulse time.
