The sim code has a lot of static initializer for options and devices, but
since they aren't using newer struct style, they have to specify a value
for every option otherwise gcc spits a lot of warnings about "missing
initializer". So add NULL/0 stubs for pointers/values.

This is the normal "passing a buffer straight to printf makes GCC warn".
While we know this particular case is fine, the trend in this source tree
is to fix this anyways to avoid the warnings.
* sim-hw.c: Use <errno.h> instead of <sys/errno.h>
(OPTION_HW_LIST): New option --hw-list to list the devices.
(hw_option_handler): List the device tree with 'sim_hw_print'.
