[PATCH 17/36] tty: serial: amba-pl011: Mark 'sbsa_uart_acpi_match' as __maybe_unused

[Lee Jones]

When !ACPI 'sbsa_uart_acpi_match' is not referenced.

Fixes the following W=1 kernel build warning(s):

 drivers/tty/serial/amba-pl011.c:2792:36: warning: ‘sbsa_uart_acpi_match’ defined but not used [-Wunused-const-variable=]
