arm: mach-k3: j721e_init: Force early probe of clk-k3 driver

Browse source 
Force the clk-k3 driver to probe early during R5 SPL boot to ensure the
default system clock configuration is completed. Many other drivers
assume a default state of the clock tree and it is currently possible
for them to probe before clk-k3 depending on the exact system
configuration.
