soc/tegra: cbb: Clear ERR_FORCE register with ERR_STATUS
[ Upstream commit a0647bca8966db04b79af72851ebd04224a4da40 ]
When error is injected with the ERR_FORCE register, then this register
is not auto cleared on clearing the ERR_STATUS register. This causes
repeated interrupts on error injection. To fix, set the ERR_FORCE to
zero along with clearing the ERR_STATUS register after handling error.
Fixes: fc2f151d2314 ("soc/tegra: cbb: Add driver for Tegra234 CBB 2.0")
