Benjamin Herrenschmidt 13e84b0bbb pp_soc_uart: Fix rx synchronizers and ensure stable tx init state 
The rx synchronizers were ... non existent. Someone forgot to add
a if rising_edge(clk) to the process.

For tx, ensure that we have a default value so that TX stays high
from TPGA configuration to the reset being sampled on the first clock
cycle.
