[PATCH v2 2/6] regmap: Use flexible sleep

[Dmitry Osipenko]

The multi-reg write function uses udelay(), which is a busy-loop based
delaying function that is not suitable for a long delays. Hence let's
replace the udelay() with fsleep(), which is flexible sleep function that
selects best delay function based on the delay-time.
