[PATCH v1 1/6] gpio: dwapb: Replace irq_shared flag with fwnode type check

[Andy Shevchenko]

Shared IRQ is only enabled for ACPI platforms or pure platform drivers,
there is no need to have a special flag for that, since we simple can test
port fwnode to be type of OF.

While at it, drop duplicate declaration of loop variable.
