Revert "i2c: tegra: Fix suspending in active runtime PM state"
This reverts commit 9f42de8d4ec2304f10bbc51dc0484f3503d61196. It's not safe to use pm_runtime_force_{suspend,resume}(), especially during the noirq phase of suspend. See also the guidance provided in commit 1e2ef05bb8cf ("PM: Limit race conditions between runtime PM and system sleep (v2)"). Signed-off-by: Thierry Reding <treding@nvidia.com>
