The boot code is using r2 and r3 to hold the page-table entry value.
While r2 is always updated before storing the value, this is not always
the case for r3.
Thankfully today, r3 will always be zero when we care. But this is
difficult to track and error-prone.
So always zero r3 within the few instructions before the write the
page-table entry.
