drivers: counter: mcux_lpit: Add clock configuration and enable

Browse Source 
Add explicit clock configuration and enable calls during driver
initialization. The driver now attempts to configure the clock
subsystem before enabling it.

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.
