debugcon: fix always print "addr=0x0, val=0x0" bug when use DEBUG_DEBUGCON

when use DEBUG_DEBUGCON, screen spits:
debugcon: write addr=0x0000 val=0x00
Rdebugcon: write addr=0x0000 val=0x00
udebugcon: write addr=0x0000 val=0x00

tdebugcon: write addr=0x0000 val=0x00
debugcon: write addr=0x0000 val=0x00

Oh, that's wrong, val is not always be 0.
this bug caused by lack of length modifier
for specifier 'x'.
