mb/google/brya/var/primus{4es}: modify GPP_B3 as unlocked
With GPP_B3 locked, primus eMMC SKU encounter eMMC storage lost after
warm reboot.
Config GPP_B3 unlocked to make reboot works on primus. Also set
GPP_B3 to low in early_gpio_table to meet eMMC-PCIe bridge IC power
on sequence.
BUG=b:221488504
TEST=USE="project_primus" emerge-brya coreboo chromeos-bootimage
test reboot 30 cycles passed on primus.
