Subject: [PATCH v2 6/7] hwrng: exynos: Enable Exynos850 support
Add Exynos850 compatible and its driver data. It's only possible to
access TRNG block via SMC calls in Exynos850, so specify that fact using
EXYNOS_SMC flag in the driver data.
Signed-off-by: Sam Protsenko <semen.protsenko@...aro.org>

Changes in v2:
- Changed QUIRK_SMC to EXYNOS_SMC to reflect the name change in the
previous patch
