a59a10dfeb drivers: Update timer APIs for Linux v6.15
In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

27e6f14c0e nvadsp: AMC and AMISC changes for multi-instance
- With multiple ADSPs in use, only one of them may configure AMC,
    so use amc_not_avlbl flag to skip reg parsing, if not needed
 - Unify reg enums for ADSP and AON; this means that reg DT prop
    for AON should have a dummy first entry (against AMC)
 - Remove adsp_prid from chip data, as AMISC base in reg DT prop
    will be offset as per the ADSP instance

e2a1904d46 nvadsp: Add multi-instance support
ADSP host driver is enhanced to be multi-instance
capable and reentrant:
 - Trailing unique identifier string in compatible DT property, like
    "adsp", "adsp1" or "aon", is used to identify the driver instances
 - Each probed driver instance is inserted into a global list, from
    which the handle can be fetched using 'nvadsp_get_handle' API
    (passing the above unique identifier as argument)
 - Above unique identifier is also used as name for the DBFS
    directory (containing files like adsp_console, adsp_logger, etc.)
 - 'nvadsp_get_handle' is the only exported API; all other APIs are
    accessible via function pointers within 'struct nvadsp_handle'
 - APIs above maintain one-is-to-one correspondence with all
    legacy APIs, with the addition of a new argument
    'struct nvadsp_handle *' at the beginning
 - Legacy APIs continue to be supported, but they are hardwired to
    work only if the kernel probes just one driver instance
 - All driver files are cleaned up to not use any global state
    variables (necessary for reentrancy)

Move stale code that uses IOMMU APIs under macro

- Added chipdata variable to indicate if amc is not available or
  relevant
- Modified aram_exit to execute only if aram size is not null
- Avoid passing fw name for registration as it currently passing "APE"
- WFI status check logic is dsp specific. Hence separated out into
  new API
- Mapping mbx interrupts is specific to AON. Hence added platform device
  specific API to map the shared interrupts
- Avoided empty interrupt spamming for level triggered interrupts.
  This fix does no harm even for edge triggered interrupts

ecf383265b drivers: Don't use strlcpy()
For Linux v6.8, the function strlcpy() has been removed. The function
strscpy() was added in Linux v4.3 and has been preferred over strlcpy().
See upstream Linux commit 30035e45753b ("string: provide strscpy()") for
more details. The Linux checkpatch.pl script warns against using
strlcpy().

The function strscpy() takes the same arguments as strlcpy(), but
returns a type of ssize_t instead of size_t. Update the drivers to use
strscpy() instead of strlcpy().

d5391a25ab drivers: Enable -Wmissing-prototypes
The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. The build failures occur because either the driver is missing
an include file which has the prototype or because the function is not
declared statically when it should be (ie. there are no external users).

Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.
