rtlwifi Modify existing bits to match vendor version 2013.02.07

These changes add the new variables for P2P and modify the various struct
definitions for other new features.

This patch updates files base.{c,h} for the changes in the newest vendor
driver.

This patch updates files ps.{c,h} for the changes in the newest vendor
driver.

This patch updates files debug.{c,h}, efuse.c, pci.{c,h}, and wifi.h for
the changes in the newest vendor driver.

This patch updates files core.c, ps.c, rc.c, and wifi.h for
the changes in the newest vendor driver.
