If the active performance monitor (v3d->active_perfmon) is being

stopped during destruction, leaving the v3d->active_perfmon pointer

due to message size and could potentially slow
down data transfer. However, an alternative
approach could be to allocate a sizable chunk of SRAM memory in
userspace. By utilizing memcpy() to copy data into
this memory, followed by a single rpmsg signal to notify the RTOS that
the data is ready, we can leverage the faster access
speed of SRAM compared to DDR from the remoteproc.

r possible solutions:
1) Add two seperate helpers ala gpu_read_power() and gpu_write_power()
where we do the if beast.
2) Add a power register offset variable to etnaviv_gpu and explicitly
use it on for reads and writes - like the Vivante driver does.
But that's just my personal opinion. Can't wait to hear what Lucas thinks.

This patch series add support for loadavg values for GPU
sub-components. I am adding a SMA algorithm as I was not
really sure if EWMA would be a good fit for this use case.
Changes v2:
