arm64: dts: rockchip: remove vdd_log from rock960 to fix a stability issues

When the performance governor is set as default, the rock960 hangs
around one minute after booting, whatever the activity is (idle, key
pressed, loaded, ...).

Based on the commit log found at https://patchwork.kernel.org/patch/10092377/

"vdd_log has no consumer and therefore will not be set to a specific
voltage. Still the PWM output pin gets configured and thence the vdd_log
output voltage will changed from it's default. Depending on the idle
state of the PWM this will slightly over or undervoltage the logic supply
of the RK3399 and cause instability with GbE (undervoltage) and PCIe
(overvoltage). Since the default value set by a voltage divider is the
correct supply voltage and we don't need to change it during runtime we
remove the rail from the devicetree completely so the PWM pin will not
be configured."

After removing the vdd-log from the rock960's specific DT, the board
does no longer hang and shows a stable behavior.

Apply the same change for the rock960 by removing the vdd-log from the
DT.

arm64: dts: rockchip: Split out common nodes for Rock960 based boards

Since the same family members of Rock960 boards (Rock960 and Ficus)
share the same configuration, split out the common nodes into a common
dtsi file for reducing code duplication. The board specific nodes for
Ficus boards are then placed in corresponding board DTS file.

Below are some of the key differences between both Rock960 and Ficus
boards:

1. Different host enable GPIO for USB
2. Different power and reset GPIO for PCI-E
3. No Ethernet port on Rock960

Only the properties which differ between both boards are placed in the
board specific dts and the reset of the nodes are placed in common dtsi
file.
