target-mips: Use cpu_reset() in cpu_mips_init()

Commit 0f71a709 (target-mips: QOM'ify
CPU) hooked up cpu_state_reset() to CPUClass::reset(). Dropping the
introduction of subclasses for 1.1, due to mips_def_t the reset code
could not be QOM'ified yet, i.e. cpu_state_reset() will not forward to
CPUClass::reset().

Update cpu_mips_init() with cpu_reset() nontheless, indirectly calling
cpu_state_reset(), so that generic code can be converted to call
cpu_reset().
