This adds support for 4000000 as secondary baudrate.
This value is selected from device tree property "max-speed"
which is then used to download FW chunks, and as operational baudrate after
HCI initialization is done.
Earlier, the secondary baudrate was fixed to 3000000 in driver, but now
with "max-speed" property, this secondary baudrate can be set to
4000000.
The secondary baudrate is set by the driver by sending a vendor command
(3F 09) to the firmware, with secondary baudrate parameter, in
nxp_post_init().
Any other value set for max-speed other than 3000000 or 4000000 will
default to 3000000, which is supported by all legacy and new NXP chipsets.
This feature is applicable for all new V3 bootloader chips and w8987 V1
bootloader chip.
This property does not apply for w8997 compatible device, since it
downloads a helper.bin FW file that sets secondary baudrate as 3000000
only.
The switch to 4000000 baudrate is validated using a Saleae Logic Analyzer
and imx8m-mini with AW693 M.2 module.

dma_fence_wait_timeout returns a long type but the driver is
only using the lower 32 bits of the retval and discarding the
upper 32 bits.
This is particularly problematic if there are already signalled
or stub fences on some of the hw planes. In this case the
dma_fence_wait_timeout function will immediately return with
timeout value MAX_SCHEDULE_TIMEOUT (0x7fffffffffffffff) since
the fence is already signalled. If the driver only uses the lower
32 bits of this return value then it'll interpret it as an error
code (0xFFFFFFFF or (-1)) and skip the wait on the remaining fences.
This issue was first observed in the xe driver with the Android
compositor where the GPU composited layer was not properly waited
on when there were stub fences in other overlay planes resulting in
visual artifacts.
