Define a new GPIO descriptor flag for marking pins that are shared by
multiple consumer. This flag will be used in several places so we need
to do it in advance and separately from other changes.

As previously documented by commit 2659392856 ("iommu/mediatek: Add
error path for loop of mm_dts_parse"), the id mapping may not be linear
so the whole larb array needs to be iterated on devicetree parsing
errors.
Simplify the loop by iterating from index zero while dropping the
redundant NULL check for consistency with later cleanups.
Also add back the comment which was removed by commit 462e768b55
("iommu/mediatek: Fix forever loop in error handling") to prevent anyone
from trying to optimise the loop by iterating backwards from 'i'.

The driver is dropping the references taken to the larb devices during
probe after successful lookup as well as on errors. This can
potentially lead to a use-after-free in case a larb device has not yet
been bound to its driver so that the iommu driver probe defers.
Fix this by keeping the references as expected while the iommu driver is
bound.
