--------------------------------

[ Upstream commit 3cbd431c ]

Amlogic G12A devices experience CPU stalls and random board wedges when
the system idles and CPU cores clock down to lower opp points. Recent
vendor kernels include a change to remove 100-250MHz and other distro
sources also remove the 500/667MHz points. Unless all 100-667Mhz opps
are removed or the CPU governor forced to performance stalls are still
observed, so let's remove them to improve stability and uptime.
