Zack Buhman 4a165d02ed sh4: fix documentation typos for SH2 instructions

These changes fix logical consistency and correctness issues with the
instruction definitions as printed in the SH4 manual.

The most serious issues were:

- div0u/div0s/div1 use `m` as a temporary variable which
  contradicts the existence of the `m` register number

- missing semicolons

- inconsistent references to immediate and displacement variable names
