Drop support for Renesas H8/300 (h8300) architecture

Possible arch problems I found (and either tried to fix or didn't):

h8300 - Is such sleeping racy vs interrupts? (See #4a).

        The H8/300 manual I found indicates yes, however disabling IRQs

        over the sleep mean only NMIs can wake it up, so can't fix easily

        without doing spin waiting.

ia64 - is safe_halt call racy vs interrupts? (does it sleep?) (See #4a)

sh64 - Is sleeping racy vs interrupts? (See #4a)
