sparc64: vcc: Enable VCC port probe and removal

Browse Source 
Enables VCC port probe and removal to initialize and terminate
VCC ports respectively. When a device/port matching the VCC driver
is added, the probe function is invoked along with a reference
to the device. remove function is called when the device is
removed.

Also add APIs to cache and retrieve VCC ports from a VCC table
