platform-modules-cel: adapt for kernel 6.12 and trixie

The following are the changes to get the modules compile:

  * Update `probe` function signature in the `i2c_driver instance dropping
    `i2c_device_id` parameter. This parameter is mostly unused in the probe
    function, if used, can be derived from the passed client pointer.
  * Remove `llseek` assignment to `no_llseek` in `file_operations`.
  * Remove `I2C_CLASS_SPD` attribute added by the modules.
  * Add missing import to `PMBUS` namespace.
  * Update `remove` function signature in the `platform_driver` and `pci_driver`
    instances, dropping return values.
  * Update `i2c_mux_add_adapter` args, dropping more than 3 args, if passed.
  * Fix `-Wint-conversion` errors occurring when `resource_size_t` is set to
    `NULL` instead of `0`.
  * Replace `strlcpy` with `strscpy`.

The following changes are done to align with trixie build (and other platforms):

  * Remove `debian/compat` file.
  * Update compat level to 13 and kernel version in `debian/control`.
  * Update `debian/rules` to use `pybuild` for non-PDDF modules and the
    conventional wheel package build for the PDDF modules. Also set shell option to
    exit upon encountering error.
  * Cleanup copying of wheel package in non-PDDF modules as the scripts are
    installed as part of debian package.
  * Make wheel package available under `build-<mod>` instead of under `modules`.

The changes are tested by building the platform packages through invoking the
below command:

  `make NOBUSTER=1 NOBULLSEYE=1 NOBOOKWORM=1 target/debs/trixie/platform-modules-dx010_1.0_amd64.deb`

Additionally, with further changes to rebranding of platform (not part of this
commit, will be raised separately) and skipping inclusion of other platforms,
verified install/boot of the `sonic-broadcom.bin` on a `DS3000` unit.

platform-celestica: config and script fixes for pddf init (#55)

The following fixes applicable to platforms (ds1000, ds2000, ds3000,
ds4000/silverstone-v2) for correct pddf intialization and access of platform
devices:

  * Update pddf-device json eliminating the need for additional indexing,
    multiplication operations in raw ipmi get.
  * The PDDF infra expects `num_components` as part of json config, update the
    same.
  * The ASIC PCIe firmware version uses `bcmcmd` to fetch the version. However,
    when syncd is not running, the error string is reported as version, fix this
    by return version as `Unknown` instead.
  * The PDDF component init passes pddf_data and pddf_plugin_data parameters,
    accommodate this.
  * Lookup correct overridden fan names from the PDDF plugin data accommodating
    fantray/psu and fan indices.
  * Lookup correct overridden thermal names from the PDDF plugin data.
  * Update platform specific monitoring service to start after `pddf-platform-init`
    service as this service imports `sonic_platform` module.
  * Update references of `/sys/class/i2c-adapter` to `/sys/bus/i2c/devices`
    instead.

Tested these changes on ds1000, ds2000, ds3000 and silverstone-v2 platforms with
accessing platform commands querying PDDF components. Verified that the accesses
to the components are ok.
