realtek: add NAND hardware description to RTL93xx
Include the NAND specs into the DTS. It is unclear which devices
really need it. Keep it disabled for now. As the SoC register area
is defined too small until now, increase the size to an appropriate
value.
If enabled one can see the following log messages (e.g. Linksys
LGS328C or LGS352C).
