bricks/primehub: fix flash memory layout

dlech · dlech · commit 6eeb48fb27af · 2020-10-09T18:38:32.000-05:00
This fixes the flash memory allocation in the linker script for SPIKE
Prime. This hub doesn't have a "user" flash memory area like other
Powered Up hubs.

Also add a comment on the RAM layout while we are touching this.
