On the smartrg sr505n the bootloader only sets registers to enable the
PHYs if it's interrupted. When Linux boots this results in a -EINVAL
error when trying to read from the EPHYs and the GPHY doesn't work.
This patch disables low power mode in the GPHY/EPHYs and properly resets
the EPHYs.

Specifications:
- SoC: Broadcom BCM63168 dual 400MHz MIPS
- Flash: 128MB NAND ESMT F59L1G81A
- RAM: 128MB DDR3
- Ethernet: 5x 1000M
- Wifi: BCM435F
- 1x USB 2.0 port
- 2x Button
- 11x LED
- Coax HPNA (unsupported)
- RJ11 xDSL (unsupported)
Install instructions:
The booloader will only install signed firmware so the image has to
be manually flashed.
- Set up a TFTP server on 192.168.1.0/24 to serve the initramfs image
- Interrupt the bootloader and run from RAM with
r 192.168.1.100:openwrt-bmips-bcm63268-actiontec_t1200h-initramfs.elf
- On the openwrt console, copy the wfi image using wget/tftp/scp, i.e
scp user@192.168.1.100:~/openwrt/bin/targets/bmips/bcm63268/openwrt-bmips-bcm63268-actiontec_t1200h-squashfs-cfe.bin /tmp/
- Erase half the flash partition where openwrt will be installed with
flash_erase -j /dev/mtd1 0 491
- Flash the openwrt image with
nandwrite -p /dev/mtd1 /tmp/openwrt-bmips-bcm63268-actiontec_t1200h-squashfs-cfe.bin
- Reboot
- Interrupt the bootloader again and use the c command to boot from
previous firmware if vendor image is loaded

[Minor improvements to DTS file]
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
Right now there's no way to know what state CFE will leave the pinctrl
registers in, so they should be explicitly set by linux on boot. This
patch adds a gpio configuration for drivers that need it, i.e. gpio-leds.

[improve patch and fix warnings]
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
The kernel logs the error "bcm6368_nand 10000200.nand: there is not valid
maps for state default" on boot and all nand pins show as UNCLAIMED in
sysfs pinmux-pins.
bcm6362.dtsi, bcm6368.dtsi and bcm63268.dtsi use the undocumented property
group which the driver doesn't understand. This has been documented upstream
in commit caf963efd4b0b9ff42ca12e52b8efe277264d35b.
Replacing group with pins allows the nand pins to be properly configured.
