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. This change is inspired by the OP-TEE OS timeout resources [1].
