This patch moves mx35 to the common timer functions added in commit
8dfafdd
- Introduce common timer functions <Rob Herring>
The (removed) mx35 timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value
cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locks the processor. Rather than patch the specific mx35 issues, simply
move everything over to the common code.
