[PULL 21/29] hw/arm/pxa2xx: Replace hw_error() by qemu_log_mask()

[Peter Maydell <peter.maydell@linaro.org>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.

When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
