The secondary SCP must wait for power state transition to complete before
sending the response back to the primary over i2c. This patch changes
the set_state parameter to request response when the power state
transition is completed. Also, a new event handling is introduced to
check the response from power domain.

This patch adds support for the sync mode set state request.
When the sync request is received by SCMI power domain it will
send an event to itself to switch the context. Then it will request
the new state from HAL. The SCMI PD will handle wait for the response
from HAL before terminating the command by responding to the SCMI agent.

This patch removes the call to deprecated function
fwk_thread_put_event_and_wait(). Also, the power domain HAL now
provides only one function to set the state.
The set_state() will return after queuing the request. Modules
that require a response will have to handle the deferred return status.

Due to a corruption issue in the trace output stream on SoC,
the drive strength and slew rate of the trace output pad signals,
both of clock as well as the data, need to be changed from their
default values at reset in the corresponding SCC regsiters.

The drive strength is bumped up to 12mA from default 8mA whilst
the slew rate is changed to FAST from the default value of SLOW.

This is a simple protocol for sending and receiving messages between
SCP and PCC using shared memory. The buffer sizes must be defined to
be identical in size. Payload sizes must be identical as well.

The protocol works by having two FIFO-style buffers in shared memory,
each processors TX buffer is mapped as the others RX buffer and vice
versa. Since it's a simple FIFO implementation, no mutexes or other
access control methods are necessary as for a given buffer, there is
only one producer and one consumer. This guarantees that messages are
processed in the order that they are received.
