5b91a8173e soc: add dummy bytes to ensure instr prefetch always valid
The CPU might prefetch instructions, which means it in some cases
will try to fetch instruction located after the last instruction in
flash.text.

Add dummy bytes to ensure fetching these wont result in an error,
 e.g. MMU exceptions

b354c11db7 esp32: Rename esp32.common.ld to esp32.project.ld to avoid build errors when downgrading
Linker script generator produces build/esp32/esp32.common.ld from
components/esp32/ld/esp32.common.ld.in

This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and
doesn't track build/esp32/esp32.common.ld at all.

At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the
linker script generated .ld file, which causes mis-builds.
