Systems that initiate frequent suspend/resume from userspace
can make the kernel aware by enabling PM_USERSPACE_AUTOSLEEP
config.

This allows for certain sleep-sensitive code (wireguard/rng) to
decide on what preparatory work should be performed (or not) in
their pm_notification callbacks.

This patch was prompted by the discussion at [1] which attempts
to remove CONFIG_ANDROID that currently guards these code paths.

Thanks, looks good to me. Do you have a corresponding Gerrit link to the
change adding this to the base Android kernel config? If so, have my
Ack:

Hi Jason,

Our latest supported kernels in Android are based on 5.15 so the
config change isn't yet needed. Once there are newer versions with the
CONFIG_ANDROID removed I will add this to the defconfig.

Thanks,
Kalesh

Jason
