serial: Compile drivers/serial/serial.c by default
Compile drivers/serial/serial.c by default both into SPL and into
non-SPL builds, since CONFIG_SERIAL_MULTI is now the default state.
Also having common/serial.c in by default now, it's pointless to keep
-DCONFIG_SERIAL_MULTI in CPPFLAGS any longer, so remove it as well.
