Use DM for the pl01x serial driver on hikey. Also migrate over to UART3 as the latest version of ATF outputs to this UART. UART3 comes out on the LS connector, rather than UART1 which goes to a unpopulated header.
NB: Upstream Linux kernel doesn't yet support UART3, so serial console will still be output on UART1 when booting a upstream kernel.
