drm/msm: Use 64 bit containers for iovas

Newer Adreno GPUs are able to support 64 bit virtual addressing. To
prepare for this brave new world switch all IOVA related variables
and members to a uint64_t container. This is harmless for the
display and older targets that do not have 64 bit addressing because
a 32 bit address is just a 64 bit address with lots of zeros. To
avoid ambiguity and compiler oddness make sure to use
lower_32_bits() and upper_32_bits() everywhere the IOVA is used to
ensure that you get what you expect.
