qpnp-fg-gen3: extend profile integrity word usage 



Currently, profile integrity register is using only bit 0 to
indicate whether the profile is loaded or not. Now that the
profile can be loaded and/or fuel gauge can be restarted by the
bootloader, extend the usage of that word by using other bits
to provide more information. This is to aid the debugging.
