realtek: refactor the Netgear GS110TPP v1 device tree

Move most of the GS110TPP v1 device tree into a dtsi so that it can be
shared with the GS108T v3.  Additionally:

  * Use macros to simplify the ethernet and switch definitions
  * Zero-pad the offsets and sizes in the partition map to 8 digits each

The spi-max-frequency value has been changed from 10MHz to 50MHz based
on an analysis of the relevant datasheets.  The current driver doesn't
use this property, as the clock speed is fixed. However, it's required
for this type of DT node, so that's why it's present here.

The firmware partition has been split in half, since this is how the
stock firmware uses it.  This can be used to easily revert to a stock
firmware if one is written to the second image area.
