Refactor the detach logic to support platform-specific implementations via
the dcfg->ops->detach callback. Allow finer control over detach behavior
depending on the remote processor management method, and make it easier
to add detach support for new SoCs.
The previous hardcoded SCU API detach logic is now moved into a dedicated
imx_rproc_scu_api_detach() function, and registered via the plat ops
structure. The generic imx_rproc_detach() now delegates to the
platform-specific handler if available.
Also, the dcfg->method check with IMX_RPROC_SCU_API is removed.

Simplify the clock enable logic by removing the dedicated
imx_rproc_clk_enable() function and integrate the clock handling directly
into the probe function to simplify the code.
Add a new IMX_RPROC_NEED_CLKS flag in dcfg to indicate whether clock
management is required for a given SoC. Update probe logic to conditionally
enable clocks based on the new flag.
Set the flag for applicable SoCs (e.g., i.MX7D, i.MX8MQ, i.MX93, etc.).

Simplify the logic in imx_rproc_start(), imx_rproc_stop() and
imx_rproc_detect_mode(), introduce start, stop and detect_mode ops for the
imx_rproc_dcfg structure. Allow each platform to provide its own
implementation of start/stop/detect_mode operations, and prepare to
eliminate the need for multiple switch-case statements.
Improve code readability and maintainability by encapsulating
platform-specific behavior.

DSP on i.MX8MP doesn't have a direct reset line so according to hardware
design team in order to handle assert/deassert/reset functionality we
need to use a combination of control bits from two modules. Audio block
control module for Run/Stall control of the DSP and DAP module in order
to do software reset.
In a first step, for i.MX8MP we are switching on using the reset
controller API to handle the DSP Run/Stall bits i.MX8MP. This comes with
the advantage of offering a better probe ordering and a more natural way
of abstracting the Audio block control bits.

On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.
Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.
By default the communication between Linux core and the remote core is
is done via a blocking mailbox mechanism but Linux doesn't allow blocking
operations in the system off (reboot, power off) handlers.
So, we need to make sure the mailbox message send operations do not block
for this specific operations. Fortunately, Linux allows us to register
handlers that are called in preparation of the system off operations.
Thus, before carrying the power off or reboot preparations, just destroy
the existing mailboxes and create them as non-blocking.
Note that power off and restart are totally different operations and are
not complementary.
We introduce a new flag in the imx remoteproc per device data which tells
us when a device needs this special setup. For now, only imx7ulp needs it.
