mips: do not place branch instructions in branch delay slot

A branch instruction in a branch delay slot confuses the execution
    pipeline and causes an exception.

bootblock.S was written 'by hand', has a branch instruction in branch
    delay slot and includes '.set noreorder' directive, which causes it to
    crash when trying to branch to main().

Adding a nop instruction fixes the problem. Also adding a nop after
    the last branch in the file just in case main() returns and the object
    linked next starts with a branch.

BUG=chrome-os-partner:31438
    TEST=Running on the simulator can reach main() now
