can: flexcan: flexcan_remove(): disable wakeup completely
With below sequence, we can see wakeup default is enabled after re-load module,
if it was enabled before, so we need disable wakeup in flexcan_remove().
| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| disabled
| # echo enabled > /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| enabled
| # rmmod flexcan
| # modprobe flexcan
| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| enabled
