[PATCH] misc/pca9552: Fix for pca9552 not getting reset

[Glenn Miles]

Testing of the pca9552 device on the powernv platform
showed that the reset method was not being called when
an instance of the device was realized.  This was causing
the INPUT0/INPUT1 POR values to be incorrect.

Fixed by calling pca9552_reset from within the
pca9552_realize method.
