drm/v3d: New debugfs end-points to query GPU usage stats.
Two new debugfs interfaces are implemented:
- gpu_usage: exposes the total runtime since boot of each
of the 5 scheduling queues available at V3D (BIN, RENDER,
CSD, TFU, CACHE_CLEAN). So if the interface is queried at
two different points of time the usage percentage of each
of the queues can be calculated.
- gpu_pid_usage: exposes the same information but to the
level of detail of each process using the V3D driver. The
runtime for process using the driver is stored. So the
percentages of usage by PID can be calculated with
measures at different timestamps.
The storage of gpu_pid_usage stats is only done if
the debugfs interface is polled during the last 70 seconds.
If a process does not submit a GPU job during last 70
seconds its stats will also be purged.

The output image is defined as being 4208x3118 pixels in size.
Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
3119 lines total.
The datasheet lists a requirement for Y_ADD_STA to be a multiple
of a power of 2 depending on binning/scaling mode (2 for full pixel,
4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
for (x4-bin)+(x2-subsample)).
(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
The current configuration for the full res modes breaks that second
requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
the same field of view as that then breaks the first requirement.
For the binned modes, they are worse off as 3118 is not a multiple of
4.
Increase the main mode to 4208x3120 so that it is the same FOV as the
binned modes, with Y_ADD_STA at 0.
Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
sensor requirements.
This does change the Bayer order as the default configuration is for
H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
and this patch has changed Y_STA_END.

BCM54213PE is an Ethernet PHY that supports PTP hardware timestamping.
BCM54210PW ia another Ethernet PHY, but one without PTP support.
Unfortunately the two PHYs return the same ID when queried, so some
extra information is required to determine whether the PHY is PTP-
capable.
There are two Raspberry Pi products that use these PHYs - Pi 4B and
CM4 - and fortunately they use different PHY addresses, so use that as
a differentiator. Choose to treat a PHY with the same ID but another
address as a BCM54210PE, which seems more common.
