delay: timeout detection support

Introduce timeout_init_us/timeout_elapsed() delay tracking with CNTPCT.

timeout_init_us(some_timeout_us); returns a reference to detect
timeout for the provided microsecond delay value from current time.

timeout_elapsed(reference) return true/false whether the reference
timeout is elapsed.

Cherry picked from OP-TEE implementation [1].
