Subject: [PATCH v2 2/7] serial: amba-pl011: get rid of useless wrapper pl011_get_rs485_mode()

Due to earlier code changes function pl011_get_rs485_mode() is now merely
a wrapper for uart_get_rs485_mode() which does not add any further
functionality. So remove it and instead call uart_get_rs485_mode()
directly.
