Commit "generic: ar8216: add mib_poll_interval switch attribute" sets
mib-poll-interval as disabled by default (was set to 2s), so it makes
switch LEDs trigger disfunctional on devices which don't have
mib-poll-interval set.
So this patch sets mib-poll-interval to 500ms on devices which have
ar83xx switch connected to mdio0 bus, as the same value was set for
built in switches in 443fc9ac35 ("ath79: use ar8216 for builtin
switch").
Some measurements performed on TP-Link Archer C7-v5:
mib-type=0, mib-poll-interval=500ms (10s pidstat)
Average: %usr %system %guest %wait %CPU CPU Command
Average: 0.00 1.93 0.00 0.00 1.93 - kworker/0:2
iperf3 (30s): 334 Mbits/sec
mib-type=0, mib-poll-interval=2s (10s pidstat)
Average: %usr %system %guest %wait %CPU CPU Command
Average: 0.00 1.14 0.00 0.00 1.14 - kworker/0:2
iperf3 (30s): 334 Mbits/sec
So it seems like we get 4x faster LED refresh rate for additional 0.8%
CPU load.

Hardware spec of DIR-859 A1:
SoC: QCA9563
DRAM: 64MB DDR2
Flash: 16MB SPI-NOR
Switch: QCA8337N
WiFi 5.8GHz: QCA9880
USB is supported on the PCB but not connected.
Flash instructions:
1. Upgrade the factory.bin through the factory web interface or the u-boot
failsafe interface.
The firmware will boot up correctly for the first time.
Do not power off the device after OpenWrt has booted. Otherwise the u-boot
will enter failsafe mode as the checksum of the firmware has been changed.
2. Upgrade the sysupgrade.bin in OpenWrt.
After upgrading completes the u-boot won't complain about the firmware
checksum and it's OK to use now.
3. If you powered off the device before upgrading the sysupgrade.bin, just
upgrade the factory.bin through the u-boot failsafe interface and then goto
step 2.
