This patch re-enables the reset_ppe() functionality for VR9 targets by using
the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function
was taken from the ppa datapath driver of lantiq UGW 7.4.1.
Additionally it adds the required reset definitions to the vr9 dtsi file.
It also prepares the reset_ppe() function calls for the other lantiq targets.
This feature is needed to be able to switch between ltq-atm/ltq-ptm driver
in ATM/PTM Auto-Mode at runtime.

We need to reset the GPHYs on reboot as well. Otherwise the bootloader
might have issues to reset/find the GPHYs.

The Lantiq XRX200 aka VR9 doesn't have an asc0. Instead,
there is an USIF module which can either be an UART or a
SPI Controller.

Updated the devicetree source files to make use of the following
upstreamed drivers:
- xrx200 ethernet phy
- reset controller unit
- dwc2
- fpi
Use our custom xrx200 ethernet phy compatible to support boards, which
have switched the vr9 revision during lifetime, with a single devicetree
source file.
By switching to the dwc2 driver + usb phy framework, we don't need to used
our custom gpio power patch and can use a fixed regulator instead.
