clocksource/drivers/nxp-pit: Prevent driver unbind

The driver does not support unbinding (e.g. as clockevents cannot be
deregistered) so suppress the bind attributes to prevent the driver from
being unbound and rebound after registration (and disabling the timer
when reprobing fails).

Even if the driver can currently only be built-in, also switch to
builtin_platform_driver() to prevent it from being unloaded should
modular builds ever be enabled.
