[PATCH 0/2] stm32 usart add fifo threshold configuration

[Erwan Le Ray]

This series adds the support for two optional DT properties, to configure
RX and TX FIFO thresholds:
 - st,rx-fifo-threshold-bytes
 - st,tx-fifo-threshold-bytes
This replaces hard-coded 8 bytes threshold. No functional change expected
if unspecified (keep 8 as default).
