Yoshihiro Shimoda c4f922e86c net: renesas: rswitch: Add spin lock protection for irq {un}mask
Add spin lock protection for irq {un}mask registers' control.

After napi_complete_done() and this protection were applied,
a lot of redundant interrupts no longer occur.

For example: when "iperf3 -c <ipaddr> -R" on R-Car S4-8 Spider
 Before the patches are applied: about 800,000 times happened
 After the patches were applied: about 100,000 times happened

Fixes: 3590918b5d ("net: ethernet: renesas: Add support for "Ethernet Switch"")
