Delete vfe_isr_ops. In all cases the right function can just be called
directly.
From vfe_hw_ops:
- enable_irq_common is completely dead
- isr_read/violation_read dont need ops (call right function directly)
- reg_update/reg_update_clear moved to gen1 ops, vfe-170 can call the
right function directly
This reveals dead function in vfe-170 which are deleted. comp_done IRQ
handling is also removed for vfe-170 - only RDI is supported.
