Subject: [PATCH v1] net: dsa: realtek: rtl8365mb: add missing case for digital interface 0

when bringing up the switch on a Netgear WNDAP660, I observed that
no traffic got passed from the RTL8363 to the ethernet interface...

Turns out, this was because the dropped case for
RTL8365MB_DIGITAL_INTERFACE_SELECT_REG(0) that
got deleted by accident.

RTL8365MB_DIGITAL_INTERFACE_SELECT_REG(0) is shared between
extif0 and extif1. There's an extra
RTL8365MB_DIGITAL_INTERFACE_SELECT_MODE_MASK later on to diffy
up between bits for extif0 and extif1.
