kdb and NMI watchdog

[Jim Houston <jim.houston@xxxxxxxxxxx>]

Hi Keith,

We noticed that kdb can trigger the NMI watchdog if a relatively
slow baud rate is used on the serial console and kdb produces too
much output.  The attached patch adds touch_nmi_calls() to
kdb_printf after each console write call.
