bcma: Replace mdelay with usleep_range in bcma_pmu_resources_init
After checking all possible call chains to bcma_pmu_resources_init() here, my tool finds that this function is never called in atomic context, namely never in an interrupt handler or holding a spinlock. Thus mdelay can be replaced with usleep_range to avoid busy wait. This is found by a static analysis tool named DCNS written by myself.
