[U-Boot] [PATCH 1/4] ARM: mx6: ddr: Make debug prints work with tiny printf

[Marek Vasut]

The %08X format returns just zeroes with tiny printf, which is
horribly confusing, especially when debugging DRAM calibration
problems. Change the format to %08x (with lowercase x), which
behaves correctly with either implementation of printf in SPL.
