[PATCH] sim: cast away hw/device differences

[Mike Frysinger <vapier at gentoo dot org>]

When building with device and hw support, the sim-core code generates a
lot of build time warnings such as:

./../common/sim-core.c: In function 'sim_core_map_attach':
./../common/sim-core.c:198:7: warning: passing argument 1 of 'device_error' from incompatible pointer type
../common/sim-core.h:347:6: note: expected 'struct device *' but argument is of type 'struct hw *'
./../common/sim-core.c:235:7: warning: passing argument 1 of 'device_error' from incompatible pointer type
../common/sim-core.h:347:6: note: expected 'struct device *' but argument is of type 'struct hw *'

In reality, these two structures get cast back and forth in the core
code already and so are "compatible".  So tweak the three functions
that generate all of these warnings to include the casts automatically.
I know this isn't exactly clean, but the current device/hw ifdef
approach is full of landmines itself and I'm not entirely sure how
to unscrew it.

	* sim-core.c (WITH_HW): Add device casts to device_error,
	device_io_read_buffer, and device_io_write_buffer.
