hw/timer/exynos4210_mct: Replace hw_error() by qemu_log_mask() 

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().

Per the datasheet "Exynos 4412 RISC Microprocessor Rev 1.00"
Chapter 25 "Multi Core Timer (MCT)" figure 1 and table 4,
the default value on the APB bus is 0.
