Some of user space daemon like ADB queries endpoint descriptor using
ioctl to know wMaxPacketSize value. Based on wMaxPacketSize value it
queues additional buffer to read zero length packet if expected read
buffer size is multiple of wMaxPacketSize. Currently driver is missing
handling for super speed plus case which results into sending full
speed related USB endpoint descriptor (i.e. wMaxPacketSize 64 bytes).
Hence when adbd is expecting 64 bytes packet from host, it queues one
more additional buffer. This results into mismatch of ADB command and
response when multiple ADB commands are used and causing different ADB
related stability issues. Fix this issue adding super speed plus check
with FUNCTIONFS_ENDPOINT_DESC ioctl command.

This change updates USB function drivers to assign SSP descriptors
using usb_assign_descriptors() API. USB SSP descriptors are needed
to enumerate these functions as different composite device in
super speed plus mode.

CONFIG_QCOM_SPMI_TEMP_ALARM is incorrectly disabled in
lahaina_QGKI.config and lahaina_debug.config. Remove this
disablement so that the SPMI temp alarm driver is compiled
in both GKI and QGKI builds.

DP driver needs to use both USB SS lane in some use case. Hence
to release USB SS lane, add dwc3_msm_release_ss_lane() API which
performs below operations:
i. Stop USB host mode
ii. Start USB host mode into high speed mode if USB host mode
was active.
dwc3_msm_release_ss_lane() API is blocking call, and will comeback
once above both operations are performed.

Since eCP will need these register writes as well, instead
of exporting a function set_secvid, move these register writes
to respective target specific functions which are common to
both eCP enabled and disabled configurations. This also helps
get rid of the register offset definitions.

With eCP, we will no longer be using the dispatcher. And
we will have different first open functions depending on
whether eCP is enabled or disabled. Hence, move dispatcher
init to first open so that dispatcher is initialized only when
eCP is not enabled.

We need APRIV enabled for eCP as well. But eCP doesn't

which is called by eCP as well.

We should not be doing anything specific to preemption like

As the name suggests, the first_open is called when the device
is opened for the first time. And last_close is called when last
device instance is closed. This helps with differentiating eCP
and non eCP open within adreno namespace.

The for loop in dwc3_msm_update_bus_bw() was using a NULL
condition rather than against ARRAY_SIZE(mdwc->icc_paths).
This can result in an out-of-bounds access if the memory
just beyond the array also happens to be non-zero.
