Remove hard-coded RTT address and get it from memory map. Change RTT initialization to keep existing buffer contents if buffers are valid. Allow more channels in the control block than defined at compile time (they will not be usable by the userspace driver). JIRA: RTOS-754
Rename RTT_CHANNEL_* to RTT* JIRA: RTOS-754

Allows for UART-like devices to be created which transmit data over RTT.
Description
Console can be defined to use either UART (as before) or an RTT channel. For now it is not possible to have console through both UART and RTT.
Each RTT channel can be configured to work in non-blocking or blocking mode. In non-blocking mode data is discarded if there is no space left in the buffer. In blocking mode the code attempts to detect if there is a host receiving data over the RTT interface and if there is, the code waits a pre-defined period until there is space left in the buffer.
Motivation and Context
With this change it is possible to access console (e.g.
psh) over RTT interface.Types of changes
