MHI controller needs to handle the fatal error callback issued by the
bus in case reset separation needs to be supported. This state will
occur as a SYS ERROR state with the device being in PBL. Perform a
full power cycle and issue an MHI RESET during power down.

MHI clients can unbind driver from userspace while a channel
is active with ongoing transfers. As we can only do host side
clean-up of the channel without sending a reset channel command
to the device, a kernel panic could occur due to incoming
packets if we proceed. Wait until the client unprepares the
channel or device goes to an error state.

If the device enters RDDM when the host is in a fast/DRV suspended
state, MHI host may end up skipping the check from BHI interrupt
handling as a host resume may remain pending for a while. Once the
host resume is triggered by the controller, MHI host can either
walk the primary event ring to discover the RDDM EE event or check
the execution environment post the DRV resume and notify the
controller of the error condition as fallbacks to the original
method of using the BHI interrupt.

Allow a move to SYS_ERROR if its arrival precedes that of an
RDDM entry notification so that the core driver remains inactive
for that period in its anticipation.

Set the RDDM support boolean at power up for MHI to know that the
device can enter RDDM execution environment. It can decide to skip
SYS_ERROR handling based on the boolean whereas allow other aspects
such as collection ramdumps if sufficient support is present.

If a controller supports RDDM, there is no need to process a SYS_ERROR.
Hence, we can safely move the power down state check to reside within an
RDDM supported controller as it allows for other controllers to handle
scenarios such as receiving an early SYS_ERROR when in the PBL execution
environment.

As of now, there is no way for MHI to know if device supports RDDM
and host controller wishes to skip ramdump collection. Allow for
that by letting the controller set the rddm support boolean which
indicates device side support. If rddm_size is set to zero while
the support for RDDM is present, that indicates disinterest in
ramdump collection if RDDM execution environment is entered.

When bringing up a new device attach to the host driver, MHI
controller can have more than one debug mode to allow for
configurable versions and make it easier to choose firmware
images and allow/disallow forced suspend/resume done to choose
new PHY settings.

1. Fix to format context correctly as expected by
hardware for system KDF.
HWKM reverses bytes at a 8-byte boundary while getting
the context from cryptolib. Reformat the context in the
command packet in such a way that HWKM receives it in the
correct order. Also, pad the context to a 8-byte multiple
as the way HW would pad it is not expected.
2. Use context for FBE to match with the one
for VTS test cases.
