New delay(), more carefully coded:
- Use explicit assembly; don't want the compiler optimizing things too
- Subtract 2 for each iteration of the loop, rather than 3. The loop
consists of only 2 instructions (even the C version compiled to a
loop of 2 instructions).
The latter change has squashed a fairly annoying timing bug in the
mii_bitbang module as used by the `ex' driver on my AlphaStation 500.
XXX delay() should maybe be rewritten again, to use the rpcc instruction.
