[PATCH] mfd: arizona: Move chip reset to before register patch

[Charles Keepax <ckeepax@opensource.wolfsonmicro.com>]

In the absence of a physical reset line the chip is reset by writing the
first register, this was done after the register patch was applied which
negates the settings applied in the register patch.

This patch moves the reset to take place before the register patch is
applied.
