[PATCH v1 1/1] regmap-irq: Consistently use memset32() in regmap_irq_thread()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The commit 4d60cac951fd ("regmap-irq: Add no_status support") adds
an additional branch into IRQ thread handler in regmap. It wisely
chose to use memset32() as it might be optimised on some architectures
and hence give a performance benefit. At the same time the old code
continue using simple memset(). Update the old code to use memset32().
