Currently shell UART backend is interrupt driven if UART driver is interrupt driven. That can be limitation if one instance wants to use interrupts but shell UART should not. Added option to shell uart to be able to control use of interrupts. By default interrupts are enabled if driver supports it. Signed-off-by: Krzysztof Chruscinski <krzysztof.chruscinski@nordicsemi.no>

RX ring buffer size impacts accepted latency of handling incoming
|
|
bytes by shell. If shell input is coming from the keyboard then it is
|
|
usually enough if ring buffer is few bytes (more than one due to
|
|
escape sequences). However, if bulk data is transferred it may be
|
|
required to increase it.
