Peter McGaughey 3104ad0e39 drivers: serial: uart_sam0: fix uart_sam0_irq_update TXC reset 
drivers: serial: uart_sam0: fix uart_sam0_irq_update TXC reset bug

uart_sam0_irq_update function resets flags that will cause int. re-entry
existing implementation also clears the TXC flag if it is set
this breaks transmit complete detection

Per the SAMD5x/E5x Datasheet Sect. 34.8.6, writing '1' to the TXC will
clear the flag and disable TX complete interrupts, this should be
preserved through the irq_update for use in the tx_complete check function

The proper fix will cache the TXC value before conditionally clearing the
flag based on that cached value. If you do not condition this on the
cached value a race condition will periodically occur where
the TXC is cleared but never cached.

Fixes zephyrproject-rtos#55386
