Andrew Tridgell fc0b2ef920 HAL_ChibiOS: added half-duplex protection for non-inverted 
to prevent output bytes being seen as input bytes we disable half
duplex during transmit. This was previously only done for non-inverted
UARTs. This patch enables it whether we are inverted or not. This
greatly reduces the number of bad input bytes.

Andrew Tridgell 8b93e0f57d HAL_ChibiOS: prevent double init of USB 
this prevented init of USB CubeBlack on Windows. Thanks to Randy for
reporting

Andrew Tridgell e8ab35a192 HAL_ChibiOS: fixed stdout in early startup bug 
this caused a failure to boot on some boards if they tried to print
messages in early startup code before hal was initialised

thanks to @Shadowru for reporting the issue
