arm: pxa: use common timer functions This patch moves pxa to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) pxa 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 locked the processor. Rather than patch the specific pxa issues, simply move everything over to the common code.
