serial: fix driver_name conflicts
Some drivers are using too generic "serial" name for driver_name, this
might cause issues, like this:
Freescale QUICC Engine UART device driver
proc_dir_entry 'serial' already registered

^^ The board is using ucc_uart.c and 8250.c, both registered as
"serial".
This patch fixes two drivers that are using "serial" for driver_name and
not "ttyS" for dev_name. Drivers that are using "ttyS" for dev_name, will
conflict anyway, so we don't bother with these.
