sh: Convert Dreamcast support from hw_interrupt_type to irq_chip
Switch the dreamcast IRQ code over to the irq_chip way of doing things,
so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards.
Also, whilst I'm here change some things to make checkpatch.pl happy:
- Indent with tabs, not with spaces
- Include <linux/io.h>, not <asm/io.h>
- Fix the multi-line comment style
- Fix some typos in the comments
