drm/tegra: hub: Use fn parameter directly to fix Coccinelle warning
The function parameter out can be used directly instead of assigning it
to a temporary u64 variable first.
Remove the local variable tmp2 and use the parameter out directly as the
divisor in do_div() to remove the following Coccinelle/coccicheck
warning reported by do_div.cocci:
WARNING: do_div() does a 64-by-32 division, please consider using div64_u64 instead
