The lines-initial-states property was an early attempt to set the latch
bit of the shift register on driver probe. It is not implemented in the
driver and was rejected upstream. The latch bit was always set by a GPIO
hog, so this property is safe to drop.

This patch fixes the previous commit that rendered the
devices (mostly leds) useless.

>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 adds firmware partition compatible for the
AVM FRITZ!Box 4020 and AVM FRITZ!WLAN Repeater 300E.
This allows to select the correct mtdsplit parser
instead of trying all available ones one by one.

Buttons of AVM FritzBox 4020 are incorrectly flagged as active high.
This was an oversight as RFKill button was working as expected even
with incorrectly flagged GPIO.

A few words about the shift-register:
AVM used a trick to control the shift-register for the LEDs with only 2
pins, SERCLK and MOSI. Q7S, normally used for daisy-chaining multiple
shift-registers, pulls the latch, moving the shift register-state to
the storage register. It also pulls down MR (normally pulled up) to
clear the storage register, so the latch gets released and will not be
pulled by the remaining bits in the shift-register. Shift register is
all-zero after this.
For that we need to make sure output 7 is set to high on driver probe.
We accomplish this by using gpio-hogging.
Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1).
Firmware can be uploaded like following:
ftp> quote USER adam2
ftp> quote PASS adam2
ftp> binary
ftp> debug
ftp> passive
ftp> quote MEDIA FLSH
ftp> put openwrt-sysupgrade.bin mtd1
Note that this procedure might take up to two minutes. After transfer is
complete you need to powercycle the device to boot OpenWRT.
