Masayuki Ishikawa f7937d11a2 arch: arm64: Fix qemu_pl011_txint() in qemu_serial.c
Summary:
- I noticed that the nsh prompt can not be shown when disabling
  debug features. Actually, the prompt will be shown when a user
  input happens.
- This commit fixes this issue by adding uart_xmitchars() as
  other serial drivers do.

Impact:
- None

Testing:
- Tested with qemu-armv8a:netnsh on QEMU-7.1
