[RESEND][PATCH 2/2] common: clarify help text for CONFIG_CONSOLE_ACTIVATE_* options

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

CONFIG_CONSOLE_ACTIVATE_NONE is an unfortunate name. The help text
explains how consoles are still activated, but omits the main way they
are activated: The device tree's /chosen/stdout-path property.

Similarly, CONFIG_CONSOLE_ACTIVATE_(FIRST/NONE) don't talk about the
implications of selecting them, so reword the help texts to better
inform the user.
