4feead71fa 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
Call Trace:

^^ 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.

56626f335b [POWERPC] QE: UCC nodes cleanup
- get rid of `model = "UCC"' in the ucc nodes
  It isn't used anywhere, so remove it. If we'll ever need something
  like this, we'll use compatible property instead.
- replace last occurrences of device-id with cell-index.
  Drivers are modified for backward compatibility's sake.
