HAL_ChibiOS: prevent hw flow control from hogging a DMA channel
...
When hw flow control is enabled check the CTS pin before we grab the
DMA channel to prevent a long timeout trying to send to a blocked port
from holding a DMA channel against another device

HAL_ChibiOS: fixed remapping of ioline_t with BRD_ALT_CONFIG
...
when a peripheral is made available via BRD_ALT_CONFIG we need to
remap the existing ioline_t in the UART and I2C drivers to use the new
pin.
This fixes an issue with half-duplex, inverted, swapped UART pins for
protocols like FPort and FPort2

HAL_ChibiOS: fixed a race condition in UART DMA transmit
...
this fixes an issue seen on one board which caused a watchdog on high
uart DMA load. We have reproduced the issue on another board by
forcing a very high DMA transfer rate on the same DMA channel while
also requesting very high transfer rates on the UART. The likely race
is in the DMA transmit timeout code, and the simplest fix is to lock
out interrupts during the DMA setup to ensure the tx timeout cannot
trigger during the setup
