* This function will initialize a portal device and put it under control of

*
* Portal is a device that connect devices
*
* Currently, you can only connect pipes in portal. Pipes are unidirectional.
* But with portal, you can construct a bidirectional device with two pipes.
* The inner connection is just like this:
*
* portal0 portal1
* read || || write
* <--<---||<---<---||<---<-- (pipe0)
* || ||
* -->--->||--->--->||--->--> (pipe1)
* write || || read
*
* You will always construct two portals on two pipes, say, "portal0" and
* "portal1". Data written into "portal0" can be retrieved in "portal1" and
* vice versa. `rx_indicate` and `tx_complete` events are propagated
* accordingly.
*
* @param portal the portal device
* @param portal_name the name of the portal device
* @param write_dev the name of the pipe device that this portal write into
* @param read_dev the name of the pipe device that this portal read from
*
* @return the operation status, RT_EOK on successful. -RT_ENOSYS on one pipe
* device could not be found.
