doc: clarify arch support for power platforms 
Add specifics as to the level of hardware supported for
power platforms.  Power 8 is the first processor level to
support ppc little endian.  Set the minimum level
for AIX to Power7 for Node version 8 and later.
This will allow the potential to leverage new instructions
and optimizations going forward.  We have spoken to the
AIX team and they agree this makes sense. Earlier processor
levels will continue to be supported for version 4.x and 6.x
on AIX.

Nit: can you remove the commas, elsewhere they seem to be used as or (x64, arm = x64 or arm, ppc64le >=power8 means ppc64le and power8)?

ppc64le, >=power8 -> ppc64le >=power8
ppc64be, >=power7-> ppc64be >=power7
