regulator: max20086: Change enable gpio to optional

Browse Source 
commit e8ac7336dd62f0443a675ed80b17f0f0e6846e20 upstream.

The enable pin can be configured as always enabled by the hardware. Make
the enable gpio request optional so the driver doesn't fail to probe
when `enable-gpios` property is not present in the device tree.
