power pins of stdcells

Hi

I updated the procedure to get the associated net connectivity, use '-net' option. If a PG term is not hooked up with global net connection, it'll report '0x0'.

Here is some usage example:

Pin only:

encounter> findPGTerms -inst /A/B/C -termType power

VCC VDD VPP

Pin and net:

encounter> findPGTerms -inst /A/B/C -termType power -net
{VCC vaa2v8_otpm} {VDD vdd_otpm} {VPP VPP_0}
