mfd: Make twl4030 SIH SPARSE_IRQ capable
twl4030 is using a two level irq controllers infrastruture.
So far, only the first level was using dynamic irq_desc allocation
to be able to have irq_domain support for device tree.
There is a need to allocate separate irq_descs for the SIH too to
avoid hacking the first level with interrupts from the second level.
Add an irq_base parameter to allow the caller to provide the base from
pdata or from dynamic allocation.
Affect TWL4030_NR_IRQS to the twl-core IRQs only.
Moreover that will allow the extraction of the of_node pointer for further
Device Tree conversion.
