sh/intc: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

Browse Source 
Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Also replace generic_handle_irq with generic_handle_irq_desc() to avoid
looking up irq_desc again.
