When mapping a non-page-aligned scatterlist entry, we copy the original
offset to the output DMA address before aligning it to hand off to
iommu_map_sg(), then later adding the IOVA page address portion to get
the final mapped address. However, when the IOVA page size is smaller
than the CPU page size, it is the offset within the IOVA page we want,
not that within the CPU page, which can easily be larger than an IOVA
page and thus result in an incorrect final address.
Fix the bug by taking only the IOVA-aligned part of the offset as the
basis of the DMA address, not the whole thing.

A recent patch added calls to of_irq_count() in the qcom pinctrl
drivers and that caused module build failures because
of_irq_count() is not an exported symbol. We shouldn't export
of_irq_count() to modules because it's an internal OF API that
shouldn't be used by drivers. Platform drivers should use
platform device APIs instead. Therefore, add a platform_irq_count()
API that mirrors the of_irq_count() API so that platform drivers
can stay DT agnostic.

batadv_iv_ogm_orig_del_if removes a part of the bcast_own which previously
belonged to the now removed interface. This is done by copying all data
which comes before the removed interface and then appending all the data
which comes after the removed interface.
The address calculation for the position of the data which comes after the
removed interface assumed that the bat_iv.bcast_own is a pointer to a
single byte datatype. But it is a pointer to unsigned long and thus the
calculated position was wrong off factor sizeof(unsigned long).

"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.
However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.
Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.
For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.
Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.
