Change log:
PATCH v3
Based on Sudeep Holla's review comments, the implementation can
be simplified by using the two flags: IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND. This patch enables the flags in the
struct irq_chip and removes the unnecessory syscore_ops callbacks.

i.MX8QM integrates a new version of FTM IP block. It adds eight
