ls1021a: Turn off DEBUG_SPINLOCK config
This debug option should be off in the release defconfig.
Enabling this debug option has significant impact on
CPU utilization and overall system performance.
i.e.:
Networking Tx throughput tests with PKTGEN show a throughput
loss of up to 10% when this debug config option is enabled.
