[ Upstream commit 916aa36042db8ee230543ffe0d192f900e8b8c9f ]
Building the driver on xtensa fails with
tensa-linux-ld: drivers/clocksource/timer-tegra186.o: in function `tegra186_timer_remove': timer-tegra186.c:(.text+0x350): undefined reference to `__udivdi3'
Avoid the problem by rearranging the offending code to avoid the 64-bit divide operation.
