Add bootph-pre-ram property for all the nodes used in SPL stage,

mcu_timer0: timer@40400000 should be part of your list.
Maybe you are referring to mcu_timer1. mcu_timer1 will be a part of u-boot.dtsi as we need to edit the node for removing k3_clks and power-domains properties from it. So we should add bootph-pre-ram
there itself in uboot.dtsi as the node will be already there.
