[U-Boot] [PATCH] mmc: Align MMC_TRACE with tiny printf

[Marek Vasut]

The tiny printf implementation only supports %x format specifier,
it does not support %X . Since it makes little difference whether
the debug output prints hex numbers in capitals or not, change it
to %x and make the MMC_TRACE output work with tiny printf too.
