HDLCD driver can request CDCEL937 driver to perform a
set_rate_from_index. Since the response will be PENDING, it needs to
bind "as a HAL" to the CDCEL937 driver. So that it can receive the
request back from the driver, CDCEL937 needs to bind back to HDLCD for
HDLCD0 and HDLCD1 clock instead of binding back to the clock HAL.

This patch adds support for the PSU driver of the
XRP7724 component of the juno board.

It provides an implementation for the PSU driver API and
uses the I2C HAL API to make PSU request to the XRP7724
component.

Enable multiple SET_OPP requests to be serviced as a single
'collapsed' request where the data from the last service request
overrides the earlier requests.

Some requests cannot be allowed to fail. This patch adds retry
functionality.

Always set frequency regardless of voltage. If the requested voltage
is equal to the actual voltage but the frequency has not yet been set
we go ahead and set the frequency.

There is a bug in the HDLCD clock driver when it stores the ID of
the clock which is currently waiting for a PENDING request. The
clock ID is stored once for the module, so if requests are initiated
for multiple devices the clock ID of the last request will
overwrite the clock ID of the request which is actually in progress.
So we fix this by handling only one request at a time.

The CDCEL937 clock driver stores the address to return the clock rate in
the clock device context before it creates an event to read the rate.
If the get_rate() event is not created because another request is
already in progress the target address will have been overwritten.
Remove the unused rate address from asynchronous request code path.

shutdown/reboot commands from OS triggers system power shutdown
routine and currently this routine calls the set_state API from
ppu_v1 driver for shutting down the cores/clusters if shutdown
API is not implemented. Platforms may hang in indefinite while
loop in set_state API and the shutdown/reboot request may never
complete.

This patch adds a dummy shutdown API returning FWK_SUCCESS so
that the shutdown/reboot process continues as the CPU context
is not crucial during shutdown/reboot. This function is open
for addition to accommodate a proper routine for shutdown.

Currently, when a notification is sent, the source identifier
of such notification is set up by the framework to the entity
of the target for the event being processed.

With this change, the framework does not overwrite anymore
the source identifier of the notification event if the provided
source identifier is a valid entity identifier.

This change allows the use case where a module processing the
current event calls another module API and the called entity
needs to send a notification. In this scenario the called module
can simply provide a valid source_id for the outgoing notification
event.
