apalis-tk1: add note about non-working gpio inits
Add a note about the non-working apalis_tk1_gpio_inits table caused by
a reservation failure. If it wouldn't be run in SPL without anything
ever getting printed one would see the following:
A: dir_input: error: gpio A1 not reserved
Please note: The current workaround is to configure pull-up/downs in
the apalis_tk1_pingrps table further below.
