pinctrl: cy8c95x0: Fix pin control name to enable more than one

The Cypress GPIO expander is an I²C discrete component. Hence
the platform may contain more than one of a such. Currently
this has limitations in the driver due to same name used for
all chips of a type. Replace this with device instance specific
name.
