Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handling
- Remove SSYNC()
- Use irq_to_gpio where applicable
- Remove gpio_edge_triggered bitfield, check irq_desc fields instead.
- Remove gpio_both_edge_triggeredb bitfield, check irq_desc fields
instead.
- Use BITMAP and bitops on gpio_enabled
- Preferably use 32-bit
- Looking at the disassembly this indeed saves quite a few instructions.
