There is a potential race for tx/rx dma requests between
msm_startup() and irq handling, for cases where dmas are not
available. This results in irq path trying to do dma mapping,
resulting in data abort. For example, consider below scenario
where rx handler reads the intermediate value of dma->chan,
set in msm_request_rx_dma(), and tries to do dma mapping,
which results in data abort.
uart_port_startup()
msm_startup()
request_irq()
...
msm_request_rx_dma()
...
dma->chan = dma_request_slave_channel_reason(dev, "rx");
<UART RX IRQ>
msm_uart_irq()
msm_handle_rx_dm()
msm_start_rx_dma()
dma->desc = dma_map_single()
<data abort>

Currently MIDI function supports only upto HighSpeed
enumeration. Add descriptors for SuperSpeed mode
and bind them to enable SuperSpeed enumeration of
USB MIDI function.

The WLAN host driver is allocating the memory from pre-alloc pool
during insmod/wlan start up before WLAN driver register and
release the pre-alloc memory after driver unregister/remove.
The Pre-alloc memory leak check and reset in Icnss platform driver
on probe failure and after remove will leads to invalid memory
leak stat and dangling pointer for wlan host driver allocated memory
from the pre-alloc memory pool.
To fix the above issue remove the pre-allaoc memory leak
check and pre-alloc memory pool reset from the icnss platform
driver and export symbol for the pre-alloc memory leak check
and pre-alloc memory pool reset.

This change defines upto 3 instances of external mdm9x45 modems in
device-tree which would need to be controlled by esoc (external esoc)
driver. The device-tree nodes allows the configuration of the external
modems (like the GPIO pins used to communicate status of modem) to be
specified.

In certain scenarios, modem shutdown requests are handled in
userspace. Enhance request engine of esoc driver to send
shutdown requests to userspace.
Also, during a shutdown, avoid setting status to 0, if line is
not a power source. There can be multiple mdms monitoring status
line. This can otherwise be misinterpreted as an unexpected reset
by other mdms.

During an unexpected reset or error fatal, update the
crash status to SSR. This is important for the drivers
listening at SSR related kernel notifier calls, where
crash status is also passed as a data payload.

SSR failures are considered fatal and results in system panic.
In certain scenarios system can continue to work even with a
failed subsystem.
Add an option in subsystem descriptor to relax on ssr failures.
