ARM: dts: amlogic: meson8b: fix reference to unknown/untested PWM clock

Browse source 
Device-tree expects absent clocks to be specified as <0> (instead of
using <>). This fixes using the FCLK4/FCLK3 clocks as they are now
seen at their correct index (while before they were recognized, but at
the correct index - resulting in the hardware using a different clock
than what the kernel sees).

Fixes: dbf9218619 ("ARM: dts: amlogic: meson8b: switch to the new PWM controller binding")
