commit d60d0cff4ab01255b25375425745c3cff69558ad upstream.

fin_pll is the parent of clock-controller@7e00f000, specify
the dependency to ensure proper initialization order of clock
providers.

without this patch:
[ 0.000000] S3C6410 clocks: apll = 0, mpll = 0
[ 0.000000] epll = 0, arm_clk = 0

with this patch:
[ 0.000000] S3C6410 clocks: apll = 532000000, mpll = 532000000
[ 0.000000] epll = 24000000, arm_clk = 532000000

Fixes: 3f6d439f2022 ("clk: reverse default clk provider initialization order in of_clk_init()")
