Enum value of 'tps65217_irq_type' is not matched with DT parsed hwirq
number[*].

The MFD driver gets the IRQ data by referencing hwirq, but the value is
different. So, irq_to_tps65217_irq() returns mismatched IRQ data.
Eventually, the power button driver enables not PB but USB interrupt
when it is probed.

According to the TPS65217 register map[**], USB interrupt is the LSB.
This patch synchronizes TPS65217 IRQ index.

This is why using enum for these types of assignments is sometimes
dangerous.  It's probably best to be explicit.
