Subject: [PATCH 5.11 319/775] clk: sunxi-ng: h6: Fix CEC clock

From: Andre Przywara <andre.przywara@....com>

[ Upstream commit 756650820abd4770c4200763505b634a3c04e05e ]

The CEC clock on the H6 SoC is a bit special, since it uses a fixed
pre-dividier for one source clock (the PLL), but conveys the other clock
(32K OSC) directly.
We are using a fixed predivider array for that, but fail to use the right
flag to actually activate that.
