reduce size of XIP region

Browse source 
in practice, we're not putting a 128M part out there, but merely
saving space for that amount of memory chews up 32k of page tracking
for something we will never use.

Tune that down to 64M, reducing the overhead to 16k. This also
matches the largest available HyperRam / FLASH part that we might
put into the XIP memory range.
