target/cris: Convert to CPUClass::tlb_fill
Remove dumping of cpu state. Remove logging of PC, as that value is garbage until cpu_restore_state. Cc: Edgar E. Iglesias <edgar.iglesias@gmail.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
