[PATCH] ram: k3-ddrss: drop debug() in timing-sensitive sequence

["Théo Lebrun" <theo.lebrun@bootlin.com>]

Those debug() calls might be useful, but beware. They can cause the DDR
controller to hang if we do not run the sequence quickly enough.

They usually are not an issue with upstream U-Boot and the default DDR
config, but they have become troublesome with custom DDR configs.

Drop those debug() statements that shouldn't be present in
time-sensitive code, to avoid anyone else falling into the trap.
