Currently, when an ADC7 channel is read, there is a wait time of
10 ms where an EOC (end of conversion) interrupt should happen
thereby completing the wait for ADC conversion. However, if this
wait times out, it is not handled and stale data can be read. Add
error logs to print when this wait times out as well as if EOC
bit is not set and return an error.
Also, this 10 ms wait time for EOC after requesting for a channel
conversion is not sufficient. As per the hardware recommendation
when multiple subsystems requests PMIC HW arbiter to read same
or different channels on different PMICs simultaneously, it could
take 15 ms for a good case i.e. where all the conversion requests
went through successfully. However, for a worst case where this
conversion request times out, it could take up to 500 ms before
an EOC interrupt is sent by PBS to SW. Hence, increase conversion
wait time to 501 ms so that no other channel reads can be made in
the worst case. Also print a warning when the wait time for EOC
is more than 15 ms.

Add msm performance module function calls to send
kgsl queue, submit and retired events. These events
will be accessed by userspace through msm performance
module to apply dynamic performance boosts.

Add an error log in pmic_glink_write when rpmsg_trysend fails to
send the message for a client. It will be useful for debugging.

Add PM8350B_ADC7_ICHG_FB channel to read charging current for
PM8350B. Also, update qcom,spmi-vadc.h to add ADC7_ICHG_FB and
other relevant channels that are needed for reading input and
charging current for SMB139x charger pumps along with scale
function indices.

Secure pagetable pointer in case of secure pagetable creation
failure is set to ERR_PTR. Correct the secure pagetable pointer
check in kgsl_iommu_map_secure_global to avoid invalid pointer
access when someone tries to map a secure global buffer.

When mem_buf_alloc() encounters an error after mapping the memory
in the stage-2 page tables of the VM, the SGL descriptor is not
freed in the error handling path, so free it.
