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].
[1] commit 33d30a74502b ("core: timeout detection support")
Minor:
- Remove stm32mp platform duplicated implementation.
- Add new include in marvell ble.mk
