Remove second zero of BSS

We zero the BSS in two places: once in _start() and then
again in yaboot_start(). The second time we actually get
it wrong and zero 1/4 of the BSS (since we subtract two
pointers).

Since this second zeroing is superfluous and buggy, remove
it.

While here, fix the comments in _start. It claims we aren't
clearing the BSS when we are.
