Console not work with CONFIG_CONSOLE_ACTIVATE_FIRST

Console not work with CONFIG_CONSOLE_ACTIVATE_FIRST

[Alexander Shiyan]

Hello.

Patch 05261801e9cde103b3c4df843472027c007531da changes input subsystem.
If the CONFIG_CONSOLE_ACTIVATE_FIRST is set and barebox config contain
one serial console and one input device (GPIO buttons, for example), the console stops working.
Currently I haven't found a solution for this, but the CONFIG_CONSOLE_ACTIVATE_ALL
solve the problem.

Thanks.

The GPIO buttons is registered at device_initcall time whereas the UART
console devices are normally registered at console_initcall time. I
assume either your UART driver or the corresponding device is registered
from a device_initcall when it should be from console_initcall.
