The IRQ=0 could be a valid interrupt number in kernel because interrupt
numbers are virtual in a modern kernel. Hence fix the interrupt usage in
a case if interrupt is unavailable by not overriding the interrupt number
which is used by the driver.

Note that currently Nexus 7 is the only know device which uses SMB347
kernel diver and it has a properly working interrupt, hence this patch
doesn't fix any real problems, it's a minor cleanup/improvement.

The IRQ handler calls mod_delayed_work() on power->vbus_detect. However,
that work item is not initialized until after the IRQs are enabled. If
an IRQ is already pending when the driver is probed, the driver calls
mod_delayed_work() on an uninitialized work item, which causes an oops.

CHARGER_SBS should select REGMAP_I2C since it uses API(s) that are
provided by that Kconfig symbol.

cm->emergency_stop will only be the value in the enumeration,
and cannot be less than zero, it will get an exception value.
So replace it with the corresponding value.
