e3be40a73f pwm: tegra-tachometer: Fix build for Linux v6.12
In Linux v6.12, commit f9ecc2febf6f ("pwm: Don't export pwm_capture()")
made pwm_capture an internal function and this broke the build for the
Tegra Tachometer driver. The pwm_capture() function simply calls the
drivers '.capture' callback and so fix this by directly calling the
function pwm_tegra_tacho_capture() instead. Note that the rpm_show()
function is also moved to after the declaration of the
pwm_tegra_tacho_capture() function.

951b2423a8 drivers: Fix platform_driver remove for Linux v6.11
In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update all the impacted drivers
as necessary to fix this.

9b118c56c7 pwm: tachometer: Fix build for Linux v6.10
In Linux v6.10, a pointer to a dynamically allocated 'struct device'
was replaced with a statically allocated 'struct device' in the
'pwm_chip' structure. Update the Tegra PWM Tachometer driver accordingly
to fix the build for Linux v6.10.

10fd025187 drivers: pwm: Fix build for Linux v6.8
Commit 54c86dd20bba ("pwm: Replace PWM chip unique base by unique ID")
removed the 'base' field of the 'pwm_chip' structure replacing it with
an 'id' field. The new 'id' is initialised by the PWM driver core and
does not need to be configured by the PWM drivers.

Add a test for conftest to detect if the 'pwm_chip' structure has the
'base' field and update the various PWM driver to only set this field if
present.

d9abb90f16 pwm: tachometer: Remove unused APIs
From Linux kernel version 6.0, some of the callback ops are
removed from pwm like config, enable, disable.

Remove the implementation of these callbacks for Linux kernel
version 6.0 and above. Add the required callback for version 6.0

Note: This change is not tested on V6.0. This is the compilation fix.
