Subject: [PATCH 4.19 067/280] clk: sunxi-ng: v3s: Fix TCON reset de-assert bit

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 5c59801f7018acba11b12de59017a3fcdcf7421d ]

According to the datasheet and the reference code from Allwinner, the
bit used to de-assert the TCON reset is bit 4, not bit 3.

Fix it in the V3s CCU driver.
