There is a problem with the EA8500, the switch will not work after soft
reboot, the only way to get it working again is to power cycle it
manually.
There are probably several issues in the play, it's quite hard to fix it
without having access to the actual device, so I don't see any other
option now, then revert the offending commit.

These pins seem to be used by hw exclusively, so claiming it in
kernel causes an error in syslog in k4.14+.

EA8500 has pcie2 slot unequipped.
By EA8500 hw design default pcie2 reset gpio (gpio63) is used to
reset the switch. That's why enabling pcie2 brings the switch into
a working state.
So let's just control the gpio63 without enabling the pcie2 slot.
We have to remove the pcie2_pins node so the gpio63 is not defined
twice. Because pcie2 node has a reference to pcie2_pins we have to
remove it as well.

According to OEM bootlog entry mass market devices are ipq8064 SoC
v2.0:
> socinfo_init: v6, id=202, ver=2.0, raw_id=2064, raw_ver=2064, hw_plat=0, hw_plat_ver=65536
I've checked C2600, EA8500 and VR2600v but couldn't find other
boards bootlog. I think it's safe to assume that other boards are
also v2.0. R7500 may be an exception because it was the first
device to hit the market.
So switch to v2.0 dtsi.
