arm: mach-k3: j721e_init: Move clk_k3 probe before loading TIFS

When setting boot media to load the TIFS binary in legacy boot flow
(followed by J721E), get_timer() is called which eventually calls
dm_timer_init() to grab the tick-timer, which is mcu_timer0. Since we
need to set up the clocks before using the timer, move clk_k3 driver
probe before k3_sysfw_loader to ensure we have all necessary clocks set
up before.
