was moved to clock.h, and iommu_map API
was changed with new sun kernel. Fix
this by updating code for new kernel

Up until kernel 6.1, devm_device_remove_group() was used when
removing sysfs group. From kernel 6.2 onwards,
devm_device_remove_group() is no longer supported. Thus, create

devm_device_remove_group().

to cover dual wlan card attach case. Firstly, delay

enumeration. Then pcie enumeration succeeds with
multi-devices. Secondly, supporting to write the qrtr
node instance id to PCIE register for wlan fw reading,
which can fix qmi message exchange failure if active
two Hastings devices. Thirdly, change the usage of
plat_env to support dual Hastings.

WLAN IOMMU mappings have cached attribute set whereas
ADSP IOMMU mappings do not have cached attribute set.
This is resulting in an inconsistent memory view between
ADSP SS and WLAN SS. ADSP writes to a DDR location and
WLAN HW reads from the same location but since access is
cached from WLAN side, there is a possibility of reading
incorrect values.
Fix is to use IOMMU_CACHE flag for audio smmu mappings.

And, ROME firmware download is in qcacld driver. Not in cnss driver.

and cnss_release_pm_sem. Move the protection to qcacld driver. In qcacld
driver, use wakeup source to protect ROME firmware download.

Converge dt nodes for wlan chips that share the same PCI slot
into one node.
The items in this node are split into 2 parts: common and chip
specific.
The common part will be parsed during cnss probe, such as basic
power related configuration and bus type, to power on the device
and trigger pci probe;
Chip specific part will be parsed during bus specific probe, this
part includes chip specific power and feature related
configurations.
With this change, cnss2 can support different chips on one pci
slot with the same image.

In some scenario like ssgtzd get killed, CNE and TZ go out of sync.
Consider a case where TZ notified CNE to enable WLAN HW. Now CNE
will request to CNSS to Enable WLAN HW. At the same time again TZ
notified CNE to Disable WLAN HW but due ssgtzd killed, CNE did not
wait for previous request(sent to CNSS to enable WLAN HW) and immediately
return to TZ. TZ assumes everything is done and change state to secure
mode. Now CNSS act on previous request of enabling WLAN HW but when
when checks the state it get secure mode and fails to enable WLAN
and asserts. Avoid assert in such scenarios.
