[ upstream commit f2eb3cdf14457fccb14ae8c4d7d7cee088cd3957 ]

Kconfig allows enabling console support for the SC26xx driver even when
it's configured as a module resulting in a:

ERROR: "uart_console_device" [drivers/tty/serial/sc26xx.ko] undefined!

modpost error since the driver was merged in
eea63e0e8a60d00485b47fb6e75d9aa2566b989b [SC26XX: New serial driver for
SC2681 uarts] in 2.6.25. Fixed by only allowing console support to be
enabled if the driver is builtin.
