3ccef09b4e drivers: serial: Remove an unnecessary critical section (cs) for SMP
Summary:
- I thought this cs is needed to avoid data corruption
- For example, while executing uart_xmitchar() in the interrupt
  handler on CPU0, an application running on CPU1 can call
  uart_putxmitchar() via write()->uart_write().
- In this case, taking xmit.sem in uart_write() will wait for CPU0
  to finish uart_xmitchar() because CPU0 has already taken a cs
  in uart_xmitchar() then nxsem_wait() on CPU0 takes a new cs
  inside (and release the cs when returning but it's OK)
- Then uart_write() on CPU1 disables UART TX, so uart_xmitchar()
  on CPU0 will not be called while executing uart_write() on CPU1.
- So this critical section in uart_putxmitchar() can be removed.

Impact:
- None

Testing:
- Tested with spresense:wifi_smp, esp32-devkitc:smp
