regulator: irq_helpers: duplicate IRQ name

Browse Source 
The regulator IRQ helper requires caller to provide pointer to IRQ name
which is kept in memory by caller. All other data passed to the helper
in the regulator_irq_desc structure is copied. This can cause some
confusion and unnecessary complexity.

Make the regulator_irq_helper() to copy also the provided IRQ name
information so caller can discard the name after the call to
regulator_irq_helper() completes.
