Sony ever so graciously provides GPIO line names in their downstream
kernel (though sometimes they are not 100% accurate and you can judge
that by simply looking at them and with what drivers they are used).

Add these to the Akari, Apollo & Akatsuki DTS-es to better document
the hardware.

Apollo can be considered the 'base configuration'. Akari brings
WLC_INT_N on GPIO_31 over that.

Akatsuki & Akari diff:

<                         "NC",
>                         "SAMD_RSTEN_N",

Which makes sense, as Akari and Akatsuki have a wireless charger and
Akatsuki also additionally has a super-high-end-complex-for-the-time
Samsung OLED display, as opposed to LCDs on the other Tama devices.
