pwr_avg provides an average voltage, current, and power over the last
1 minute. It's up to the battery drivers to implement this
functionality.
This change allows us to have better power tracking while minimizing
the power impact on the EC, because
- the pwr_avg command only needs to be called once every minute, and is
short, thus less expensive to parse on ECs without a UART buffer
- the work done to keep the avg is partially done by the batteries
already and it's just a question of retrieving it.

Enable deep sleep on rk3399 devices and start using SYS_RST_L to track
the AP state.
We can only release this once the EC has the proper support. It needs to
assert SYS_RST_L in S5.
If we have an old EC and this change in the Cr50 firmware, Cr50 won't be
able to tell when the AP is off. I think this will just cause an
interrupt storm on the AP UART and might not go into regular sleep in
S5.
If the EC change gets released before Cr50, Cr50 won't go to sleep in
S5, because SYS_RST_L is a wake on low pin. Cr50 will immediately wake
up from the SYS_RST_L pin when it enters sleep.

We have a requirement that this signal is asserted whenever cr50 is in

as wake on high before deep sleep, so cr50 doesn't wake up

behavior of plt_rst_l when it's used to track the AP state and enable
deep sleep.
This doesn't change anything right now, because no devices that use
sys_rst_l have deep sleep enabled.
