MSMfalcon requires the voter & voter branch clocks to be able to
enabled/disabled & set rate on these clocks from the client. Also add
support for few hardware & dummy clocks to be able to perform clock ops
from the clients.

Currently the hardware clocks are added from each clock controller
individually and are not added to the of_clk_provider. But there could be
clocks which are required by clients to be used. Add the hardware clocks to
the of_clk_provider list.

Set the POWER_SUPPLY_PROP_PD_IN_HARD_RESET when hard reset
has been issued and clear it when completed. This replaces
the previous use of PD_ACTIVE which is now used to indicate
assertively whether the port partner is PD capable or not.
As such, since charger driver now definitively knows, it is
also not necessary to explicitly change PROP_TYPE to USB_PD.

Add additional properties for USB PD usage:
- POWER_SUPPLY_PROP_PD_IN_HARD_RESET is set when PD is
undergoing a hard reset
- POWER_SUPPLY_PROP_PD_CURRENT_MAX used to indicate the
current limit as negotiated over PD
- POWER_SUPPLY_PROP_PD_USB_SUSPEND_SUPPORTED is set when
USB suspend current limit must be honored when USB bus
is suspended
Also add enums to distinguish PD activity state: inactive, active.

Support incoming VCONN Swap requests by accepting and turning
off/on VCONN.
Due to HW board limitations, if VCONN is being sourced from the
VBUS input we cannot support enabling VCONN while as a sink and
greater than 5V has been negotiated on VBUS. In that case, reject
the request. Add a device tree property that indicates whether
the board is configured for separate VCONN supply.

With PM autosleep enabled, the system may aggressively enter
and re-enter suspend in between calls to queue_work() and
when the state machine function gets executed, which may
at best result in numerous suspend/resume cycles and at
worse starve the PD state machine from even executing.
Fix this by calling pm_stay_awake() whenever the work is
queued and relinquish with pm_relax() when no further work
is to be done.

VDMs, especially structured ones, are almost always handled
as requests and responses. Hence it does not make sense to
allow more than one outgoing VDM at a time, so get rid of the
vdm_tx_queue list and simplify it to a single-issued packet.
Because port partners can only have one VDM request/response in
flight, also handle the case when a new structured request is
received before the previous response has been sent. In that
case we simply discard the queued message as it's now invalid.

As UFP since the policy engine only responds to the Discover
Identity command, all other commands are unrecognized and
therefore should be NAKed. Fix the handling as follows:
- Ensure the standard Discover Identity was sent using
SID of 0xFF00, otherwise it is invalid
- Don't NAK incoming Attention messages
- When sending a NAK, respond with the same SVID of the
initiating command, whether it was correct or not
- Enter Mode is not supported in general, but the NAK
should also be sent back with the same mode index
- Re-issue Discover SVIDs when more than 12 SVIDs are returned
- Clean up macro name prefixes from 'VDM' to 'SVDM' to
emphasize they are accessing structured VDM specific bits

Fix several issues which help address PD compliance testing:
- Soft reset should be issued instead of hard reset in cases
where an unexpected message is received.
- In source mode, send a Reject if the Request PDO object also
exceeds the advertised current capability. Fix the incorrect
bitmask in the PD_RDO_FIXED_CURR macro.
- Handle possibility of quick back-to-back RX messages by
flushing the sm worker to ensure the last message was fully
processed before overwriting the buffer.
- Discard PING messages as they are not applicable to Type-C.
- Respond to GET_SINK_CAP while in source mode, and vice
versa, respond to GET_SOURCE_CAP when in sink mode.
- Move pd->hard_reset=false to PE_SRC/SNK_TRANSITION_TO_DEFAULT
for consistency.
- Change default sink capabilities to advertise only 5V @ 900mA
since the policy engine will not automatically request higher
voltages. If userspace wants to request greater than 5V it should
also update the sink capabilities.
- Reset the protocol counters at the beginning of PE_SNK_STARTUP.
