For the next time, please don't forget to add "PATCH-v2" as it is a
second version of this patch.
Applied on stm32-next.
Thanks.

Enable focaltech ft6236 touchscreen on STM32MP157C-DK2 board.
This device supports 2 different addresses (0x2a and 0x38)
depending on the display board version (MB1407).

I'm not confident by this duplication. We should only support the latest
revision of the MB1407. I understand the need but my fear is to
duplicate this node each time we have a new revision (and imagine if we
do that for all i2c devices).

Hi Alex,
ok, i'll push only the dt patch link to the last version of driver
touchscreen on display board MB1407.
