In Linux v6.16, commit 41cb08555c41 ("treewide, timers: Rename
from_timer() to timer_container_of()") renamed 'from_timer()' to
'timer_container_of()'. Given that this is a macro we can simplfy see if
the macro 'timer_container_of' is defined and if so use this otherwise
fall back to 'from_timer()'. Update the necessary drivers to fix the
build for Linux v6.16.

cleanup & modularize driver code structure to separate
out HW dependent & independent parts to facilitate adding
support for new SoCs
This patch
- restructure SoC specific code into separate files
- Add function pointers to call HW specific sequences
- adds a common header which is needed by all platforms
- cleans up obsolete code such as memmap of phc regs,
xavier support, etc
- Removes default value assumption for lock_threshold,
pps_freq, sync_trig_interval

Add support to select initial operating mode (GPIO or TIMER)
through DT property "nvpps-event-mode-init".
This allows users to specify which mode the driver should
start in rather than always defaulting to GPIO mode if gpios
property is specified in DT.
Key changes:
- Add DT property parsing for initial event mode
- Add validation to ensure selected mode is supported
- If this property is not specified, default mode selection
happens based on if nvpps-gpios property is defined or not
- Add informative debug messages about selected mode
- Add error handling for invalid configurations(eg: init
mode is GPIO but gpios property is not defined). If
validation fails, probe returns error instead of
defaulting to TIMER mode.

Add support for configurable timestamp capture interval
through device tree property 'ts-capture-interval'.
This allows users to tune how frequently timestamps are
to be captured in TIMER mode.
- Add support for device tree property 'ts-capture-interval' (in ms)
- Defaults to 1000ms if property not specified
- Validate interval is within allowed range (100ms - 1000ms)
- Update timer configuration to use configurable capture interval

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.

As per HW suggestion we should not trigger sync on every

PTP clock.

Remove the module pointer from the class_create() based
on following change in core kernel
======
driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something. So just remove it and fix up all callers of the function in
the kernel tree at the same time.
