>From the Documentation/devicetree/bindings/leds/common.txt:
- default-state : The initial state of the LED. Valid values are "on", "off",
and "keep". If the LED is already on or off and the default-state property is
set the to same value, then no glitch should be produced where the LED
momentarily turns off (or on). The "keep" setting will keep the LED at
whatever its current state is, without producing a glitch. The default is
off if this property is not present.
So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.

This commit modifies mtd partitions define for Buffalo BHR-4GRV2 and
move it to generic subtarget.
In Buffalo BHR-4GRV2, "kernel" partition is located behined "rootfs"
partition in the stock firmware. This causes the size of the kernel
to be limited by the fixed value.
0x50000 0xe80000 0xff0000
+-------------------------------+--------------+
| rootfs | kernel |
| (14528k) | (1472k) |
+-------------------------------+--------------+
After ar71xx was updated to Kernel 4.14, the kernel size of BHR-4GRV2
exceeded the limit, and it breaks builds on official buildbot.
Since this issue was also confirmed in ath79, I modified the mtd
partitions to get rid of that limitation.
0x50000 0xff0000
+----------------------------------------------+
| firmware |
| (16000k) |
+----------------------------------------------+
However, this commit breaks compatibility with ar71xx firmware, so I
dropped "SUPPORTED_DEVICES += bhr-4grv2".
This commit requires new flash instruction instead of the old one.
Flash instruction using initramfs image:
1. Connect the computer to the LAN port of BHR-4GRV2
2. Set the IP address of the computer to 192.168.12.10
3. Rename the OpenWrt initramfs image to
"bhr4grv2-uImage-initramfs-gzip.bin" and place it into the TFTP
directory
4. Start the tftp server on the computer
5. While holding down the "ECO" button, connect power cable to
BHR-4GRV2 and turn on it
6. Flashing (orange) diag LED and release the finger from the button,
BHR-4GRV2 downloads the intiramfs image from TFTP server and boot
with it
7. On the initramfs image, create "/etc/fw_env.config" file with
following contents
/dev/mtd1 0x0 0x10000 0x10000
8. Execute following commands to add environment variables for
u-boot
fw_setenv ipaddr 192.168.12.1
fw_setenv serverip 192.168.12.10
fw_setenv ethaddr 00:aa:bb:cc:dd:ee
fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
9. Perform sysupgrade with squashfs-sysupgrade image
10. Wait ~150 seconds to complete flashing
And this commit includes small fix; BHR-4GRV2 has QCA9557 as a SoC,
not QCA9558.

Use diag.sh version used for apm821xx, ipq40xx and ipq806x, which
supports different leds for the different boot states.
The existing led sequences should be the same as before.
