m7-common: Remove deprecated bnep services

Change-Id: I43e305b2d82b7c699a7207ede084037cf5f7a5f1
m7-common: overlay vzw-specific eri.xml

The mcc/mnc specific config.xml in values-xxx and xml-xxx were
apparently copied from Sprint. I see no reason they sould have been
included in the first place. This is re-affirmed by decompiling the
frameworks apks from stock.

Include more mcc/mnc eri overlays to correct the R(oaming) symbol in 3G.

m7-common: Switch to DMIC Endfire for Speaker DMIC Endfire

* This is supposed to use DMIC4 on stock, but that appears to be
  horrible. Use DMIC Endfire setup instead.
