arm: dts: k3-*-r5: Remove clocks from mcu_timer0

Browse source 
Updated PLL driver sequencing requires us to use udelay in the PLL
driver as there is no poll bit to get the status of operations.
tick-timer(mcu_timer0/main_timer0) setting up the clocks for itself is
something that won't work as the PLL driver will be using udelay and
PLLs are configured during clock probe which would end up in a recursive
probe.

tick-timer being used by K3 devices are configured by ROM and we really
don't need to configure any of the clocks.

Remove the clock dependency from R5 stage as we don't need to setup
clocks for it.
