clocksource/drivers/exynos_mct: Explicitly return 0 for shared timer

For a shared timers, the mct_init_dt() should not initialize the clock
even with global comparator.  This is not an error, thus the function
should simply return 0, not 'ret'.

This also fixes smatch warning:

  drivers/clocksource/exynos_mct.c:635 mct_init_dt() warn: missing error code? 'ret'
