Add trivial bindings for driver which permits exposing syscon backed

counter on various platforms where the boot counter is stored in
random volatile register, like STM32MP15xx TAMP_BKPxR register.

Let me also leave a note here - cross linking for all parties:
Please propose a solution solving also mediatek,boottrap, probably
extendable to range of registers. Other solution is what Rob mentioned -
this might not be suitable for generic binding and device.
From what I can tell, shouldn't the mediatek 1g MAC driver have a
nvmem-cells phandle to this OTP/fuses/whatever area and shouldn't the
driver read out and decode its settings within the kernel ?
That doesn't seem really related to this particular issue I'm trying to
solve I'm afraid.
