openpower: pdbg: Set PV for git fetcher

Explicitly set PV according to OE convention.  From the "Fetching Code"
section of the Yocto Project Development Tasks Manual:

  Another way of specifying source is from an SCM. For Git repositories,
  you must specify SRCREV and you should specify PV to include the
  revision with SRCPV.

(From meta-openpower rev: b400ee0dd89004c227d9f1e4bf1458e701ed7553)
