drivers: pwm: mcux_tpm: Add clock configuration support

Browse Source 
Add clock_control_configure() call during initialization to properly
configure the TPM clock. The driver now attempts to configure the
clock and handles cases where configuration is not supported by the
platform (-ENOTSUP/-ENOSYS) by continuing with default settings.
Real configuration errors are logged and cause initialization to fail.

Note: -ENOSYS is temporarily ignored as not all clock control
drivers currently implement the configure API. This handling
should be removed once all clock drivers support configure.
