platform: nordic_nrf: Fix platform test timer

Fix the platform test timer configuration. The FLIH interrupt test
expects the timer to generate periodic interrupts based on the reload
value. The timer was configured to only generate a single interrupt
(oneshot mode).

Add the missing tfm_plat_test_secure_timer_clear_intr function.
