Peter Hinch d242a9b7f7 rp2/machine_uart: Use read/write mutex to prevent char duplication. 
Duplication of characters is caused by re-entrant calls from separate cores
of uart_fill_tx_fifo().  This patch uses a mutex to ensure that a
re-entrant execution of the function returns without affecting the UART
FIFO.

Fixes issues #8344 and #8360.
