[PATCH 1/2] RISC-V: Add 'H' to canonical extension ordering

[Nelson Chu]

Sorry for being late, I have been busy recently.  I didn't notice that
the isa spec had been updated, anyway, the h is a single extension
after v, rather than the multi-letter extension for now.  So LGTM,
committed.

Besides, please give me some time to review other patches, I've been
busy with other things for a while...

Thanks
Nelson
