* wait_for_bit() waits for bit set/cleared in register

* Function polls register waiting for specific bit(s) change

* - Timeout
* - User interaction (CTRL-C)
* Function succeeds only if all bits of masked register are set/cleared

* @param prefix Prefix added to timeout messagge (message visible only

* @param mask Bit(s) of register that must be active
* @param set Selects wait condition (bit set or clear)
* @param timeout_ms Timeout (in miliseconds)
* @param breakable Enables CTRL-C interruption
* @return 0 on success, -ETIMEDOUT or -EINTR on failure
