mb/google/brya/var/primus: Disable autonomous GPIO power management
Used H1 firmware where the last version number is 0.0.22, 0.3.22 or less to production that will need to disable autonomous GPIO power management and then can get H1 version by gsctool -a -f -M BUG=b:201054849 TEST=USE="project_primus emerge-brya coreboot" and verify it builds without error.
