I randomly checked one or two registers when I first attempted this
patch, but it does appear that the H1 is likely not to work yet due to
too many differences. It appears that patches 4 and 5 will likely
have to be dropped until they can be investigated and reworked.
I am still running into some power domain issues for the rest of the
series where I cannot read the regmaps for the vpu blk-ctrl register
even when H1 is disabled.
