Memory in the secure page pool cannot be used for other tasks. If the ion
client is aware that the memory will not be used for the foreseeable future
then there is no point in caching it.
Implement a method for the client to communicate this usecase to the
kernel.

Allocating an amount from the secure pool, and then freeing that amount
back to the secure pool will not necessarily increase the pool size. Fix
this by allocating from the nonsecure pool, and then freeing to the secure
pool.

In combo usecase there are 2 front-end dai's with

Buck damage was observed because the OOB comparator activated
when HSFET was on, causing a direct short from VBUS to ground. Fix this
on V1.1 by increasing the OOB comparator threshold. On 2.0 this is fixed
by ensuring the OOB comparator activates only after HSFET minimum on
time. This in turn guarantees that HSFET and LSFET won't be on at the
same time.
Since the driver needs to detect the version of the smb, make use of the
qpnp-revid module.
