In order to reduce the impact of the VPT parsing happening on the GIC,
we can split the vcpu reseidency in two phases:
- programming GICR_VPENDBASER: this still happens in vcpu_load()
- checking for the VPT parsing to be complete: this can happen
on vcpu entry (in kvm_vgic_flush_hwstate())
This allows the GIC and the CPU to work in parallel, rewmoving some
of the entry overhead.

In order to keep OTG ID detection even when in Host mode, the ID line of
the PHY (if the current phy is an OTG one) pull-up should be kept
enable in both modes.
This fixes OTG switch on GXL, GXM & AXG platforms, otherwise once switched
to Host, the ID detection doesn't work anymore to switch back to Device.

Linux now has incomplete support for the LED controller on Turris Omnia:
it can set brightness and colors for each LED.
The controller can also put these LEDs into HW controlled mode, in which
the LEDs are controlled by HW: for example the WAN LED is connected via
MCU to the WAN PHY LED pin.
The driver does not support these HW controlled modes yet, and on probe
puts the LEDs into SW controlled mode.
Add node describing the LED controller, but disable it for now.

Turris Omnia has an SFP cage that, together with WAN PHY, is connected
to eth2 SerDes via a SerDes multiplexor. When a SFP module is present,
the multiplexor switches the SerDes signal from PHY to SFP.
Describe the SFP cage, but leave it disabled. Until phylink has support
for such configuration, we are leaving it to U-Boot to enable SFP and
disable WAN PHY at boot time depending on whether a SFP module is
present.
