bootblock: Reduce register load

The common part of the bootblock resets the nvram data if it's found
    to be invalid. Since that code is compiled with romcc in i386 mode,
    there's a shortage on registers.

Try to reduce the strain by doing things smarter: cmos_write_inner
    is the same as cmos_write, just that it doesn't check if the RTC is
    disabled. Since we just disabled it before, we can assume that it is so.
