Michal Lenc 1d88bceb79 samv7: raise input flow control warning only for serial drivers
Hardware flow control for serial requires the usage of DMAC channels
which is not yet supported for SAMv7 MCU. However the same config option
CONFIG_SERIAL_IFLOWCONTROL is also used for USB CDC/ACM flow control which
works well. Therefore the warning message should be raised only if
flow control is configured for USART driver and not for USB CDC/ACM.
