pinctrl: mvebu: armada-37xx: use use platform api

Browse Source 
platform_irq_count() and platform_get_irq() is the more generic
way (independent of device trees) to determine the count of available
interrupts. So use this instead.

As platform_irq_count() might return an error code (which
of_irq_count doesn't) some additional handling is necessary.
