mfd: intel_soc_pmic_crc: Add crystal_cove_charger cell to BYT cells

Browse Source 
The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used and we need to have
a cell for this, with a driver which creates its own irqchip with
a single IRQ for the charger driver to consume.

The charger driver cannot directly consume the IRQ from the MFD level
irqchip because the PMIC has 2 levels of interrupts and the second
level interrupt status register, which is handled by the cell drivers,
needs to have the IRQ acked to avoid an IRQ storm.
