[U-Boot] [PATCH] fs/fat: debug-print file read position during file_fat_read_at()

[Andreas Dannenberg]

In order to make the debug print in file_fat_read_at() a tad more useful,
show the offset the file is being read at alongside the filename.

Small addition but helpful nevertheless as none of the other debug prints
embedded into fat.c seems to output this info. Without that addition it
would just tell you the same file name a couple of times when reading
from an DTB/ITB file for example. With the offset being shown it's easier
to correlate/debug the loading process.

Oddly (and I haven't fully debugged this) but in order to really get _any_ of
the debug() prints working in fat.c in my particulat setup, in addition to
the usual '#define DEBUG' I also had to explicitly define _DEBUG to '1',
something that should already be taken care of by log.c...
