Subject: [PATCH] serial: ar933x_uart: Fix build failure with disabled console

Patch-mainline: v5.1-rc3
References: bsc#1051510
Andrey has reported on OpenWrt's bug tracking system[1], that he
currently can't use ar93xx_uart as pure serial UART without console
(CONFIG_SERIAL_8250_CONSOLE and CONFIG_SERIAL_AR933X_CONSOLE undefined),
because compilation ends with following error:
ar933x_uart.c: In function 'ar933x_uart_console_write':
ar933x_uart.c:550:14: error: 'struct uart_port' has no
member named 'sysrq'
So this patch moves all the code related to console handling behind
series of CONFIG_SERIAL_AR933X_CONSOLE ifdefs.
