65276fdd3f utils.h: add memory clobbers 
We mostly use read32/write32 and friends to poke hardware registers,
which might have side effects on RAM, so just make everything a memory
clobber to avoid potential issues.

35e24d58d9 linkerscript: add a dummy payload section starting at EOF 
So it turns out iBoot is happy to load mach-o files with a section hanging
"off the end" of the file (it does not over-read, it just ignores the
excess). We can use this to our advantage to support appending payloads
to m1n1 with a simple `cat`.
