soc: qcom: Restore OnePlus project_info framework

This driver was omitted during initial OEM import because it is,
generally speaking, completely useless and not needed to facilitate
any core device functionality. However, it has recently been
brought to my attention that the sys/project_info/hw_id node is the
mechanism by which OxygenOS identifies McLaren Edition OnePlus 6T
devices and subsequently determines that variant-specific
cosmetic features should be enabled.

Given that project_info is only useful to us in this one highly
niche scenario we should ultimately be able to trim A LOT of fat
from this driver, preserving only the nodes needed to identify
McLaren devices. However, let's ensure that everything is now
functioning as intended for McLaren users before we go monkeying
around any further.
