There are both tegra_smmu_swgroup and tegra_smmu_group structs
using "group" for their pointer instances. This gets confusing
to read the driver sometimes.
So this patch renames "group" of struct tegra_smmu_swgroup to
"swgrp" as a cleanup. Also renames its "find" function.
Note that we already have "swgroup" being used for an unsigned
int type variable that is inside struct tegra_smmu_swgroup, so
it's not able to use "swgroup" but only something like "swgrp".
