FPC experiments: got so far TX_only, usart=115200 + usb=460800, see full commit msg

Browse source 
* Add \r\n to sent strings
* remove usart_init() from UsbPacketReceive cmd, it's already init in main.
* Add PLATFORM PM3RDV4FPC to ease dev
* TX: US_TCR is len of data to send, not len of buffer
* Use only one PDC bank as we're using it in sync
* Busy loop to wait for end of TX as we'using it in sync
* Change usart speed to 115200
* Don't downgrade USB speed, keep 460800
* Attempt to detect received data, fail so far
