[PATCH] soc: amlogic: meson-gx-pwrc-vpu: fix power-off when powered by bootloader

Arnd, Olof,

Neil Armstrong [off-list ref] writes:

In the case the VPU power domain has been powered on by the bootloader
and no driver are attached to this power domain, the genpd will power it
off after a certain amount of time, but the clocks hasn't been enabled
by the kernel itself and the power-off will trigger some faults.
This patch enable the clocks to have a coherent state for an eventual
poweroff and switches to the pm_domain_always_on_gov governor.

This fixes a patch that's currently in arm-soc next/drivers (or
amlogic/drivers-2 to be precise.)

If it's not too late, please feel free to apply directly.  If not, I
will queue up for v4.15-rc fixes cycle.

Thanks,

Kevin
