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: [cf82de50] [c0007f7c] show_stack+0x4c/0x1ac (unreliable) [cf82de90] [c00b03fc] proc_register+0xfc/0x1ac [cf82dec0] [c00b05c8] create_proc_entry+0x60/0xac [cf82dee0] [c00b23dc] proc_tty_register_driver+0x60/0x98 [cf82def0] [c016dbd8] tty_register_driver+0x1b4/0x228 [cf82df20] [c0184d70] uart_register_driver+0x144/0x194 [cf82df40] [c030a378] ucc_uart_init+0x2c/0x94 [cf82df50] [c02f21a0] kernel_init+0x98/0x27c [cf82dff0] [c000fa74] kernel_thread+0x44/0x60 ^^ 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.
