This separates the kref for ion handles into two components.
Userspace requests through the ioctl will hold at most one
reference to the internally used kref. All additional requests
will increment a separate counter, and the original reference is
only put once that counter hits 0. This protects the kernel from
a poorly behaving userspace.

Commit <be0960374> ("scsi: ufs: scale up the gear in 2 steps") introduced
a bug where we would not scale up the gear to HS-G3 if
UFS_DEVICE_QUIRK_HS_G1_TO_HS_G3_SWITCH quirk isn't enabled for UFS device.
Fix this by allowing HS-G3 scaling irrespective of quirk state.

This patch segregates different PD data onto separate buffers
and then onto its own data stream.

For some use cases, mdp clock source needs to be parked at a safe
frequency when it is disabled and force enabled in order to execute
a safe dynamic switch. Add support for the same by adding
non_local_children flag.

For branch clocks having aggr_sibling_rates flag as set, get_rate()
always returns the parents rate despite the branch clocks prepare
status. Fix the same by adding a check for branch prepare status
and aggr_sibling_rates flag value.

This enables 128 bit matching in ip6tables to help
optimize cases where there is no match required.
This shows a rough improvement of 40Mbps in a UDPv6
downlink test using iperf.

iptables matching for ipv6 always has a mask if an address is
specified for match. Adding a check for mask prior to that
helps to improve performance as it avoids the masked comparison.
This is achieved by defining a new feature IP6_NF_IPTABLES_128
which allows to perform 128 bit arithmetic while matching.

Since modem is not up these statuses are redundant and are

OLEDB_SPARE_CTL register bit is set by the PBS during the display enable
and is used during the display suspend to trigger the PBS event.
Hence, move clearing of the OLEDB_SPARE_CTL register to regulator disable.
Also enable the force_pd_ctl only for DRAX-A revisions <=2.0.
