staging: bcm2835-audio: interpolate audio delay

When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
in the audio position, aka "delay" -- the number of frames that must
be output before a new frame would be played.
Make this a bit nicer for userspace by interpolating the position
using the CPU clock.
The overhead is small -- an extra ktime_get() every time a GPU message
is sent -- and another call and a few calculations whenever the delay
is sought from userland.
At 48,000 frames per second, i.e. approximately 20 microseconds per
frame, it would take a clock inaccuracy of
20 microseconds in 10 milliseconds -- 2,000 parts per million --
to result in an inaccurate estimate, whereas
crystal- or resonator-based clocks typically have an
inaccuracy of 10s to 100s of parts per million.

staging: vboxvideo: Keep old mode when disable crtc

On DPMS off we get a call to vbx_crtc_atomic_disable, followed by
a call to vbox_primary_atomic_update, at which point crtc_state->enable
is 0 and crtc_state->mode has been zero-ed. On a 0 width/height
vbox_do_modeset() falls back to 640x480, so this causes the guest Window
(its "monitor") to resize to 640x480 (and become black).

This commit makes us not look at crtc_state->mode when crtc_state->enable
is not set, so that we keep the old mode and just make the window go black.
