tty: ar933x_uart: use config_enabled() macro to clean up ifdefs

Add a new ar933x_uart_console_enabled() helper function
which uses the config_enable(CONFIG_SERIAL_AR933X_CONSOLE)
macro to decide if the console support is enabled or not.

Remove the 'ifdef CONFIG_SERIAL_AR933X_CONSOLE' statements
and use the new helper function to conditionally enable
console support instead.

If CONFIG_SERIAL_AR933X_CONSOLE is not enabled, the new
helper function will become a null stub which allows the
compiler to optimize out the unused console specific
functions/variables.
