Subject: [PATCH] clk: rockchip: fix clock gate for rk3188 spdif_pre

In rk3188 clock branches, spdif_pre gate was set to RK2928_CLKGATE_CON(13) bit 13.
This appears to be a copy-paste error because such a register does not exist.
We correct it to RK2928_CLKGATE_CON(0) and find out that the rk3188 spdif clock
is the same as the rk3066 spdif clock, so we move it to the common clock branches.

applied to my clk branch for 3.19 after verifying the manual-values


Thanks
