Replaced a hardcoded timeout in CyH4TransportDriver.cpp with a cypress hal function. The cypress PUTC hal API only blocks until data has been send into the HW buffer, not until all data has been out of the HW buffer. Modified an API to block untill all tx transmit is complete. This allows the removal of a hardcoded timeout in CyH4TransportDriver.cpp that waits for data int the HW buffer to be sent.

The 5000 us delay was insufficient on some Cypress board which may cause the radio to go to sleep prematurely and BLE packets to be delay until the radio wakes up again.
