commit bcbf53a0dab50980867476994f6079c1ec5bb3a3 upstream.
The sram-node compatible properties have mistakingly combined the model-specific string with the generic "mtd-ram" string.
Note that neither "cy7c1019dv33-10zsxi, mtd-ram" or "cy7c1019dv33-10zsxi" are used by any in-kernel driver and they are not present in any binding.
The physmap driver will however bind to platform devices that specify "mtd-ram".

This was never meant to go into stable so I didn't add a stable CC-tag.
It causes a driver to bind to the corresponding platform devices, which have so far been unbound and may therefore have unwanted side-effects.
I don't think it's stable material either way.
