From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
On the Renesas RZ/G3S SoC, the USB PHY receives a signal from the system
controller that need to be de-asserted/asserted when power is turned
on/off. This signal, called PWRRDY, is controlled through a specific
register in the system controller memory space.
Add the renesas,sysc-signals DT property to describe the relation b/w the
system controller and the USB PHY on the Renesas RZ/G3S. This property
provides a phandle to the system controller, along with the offset within
the system controller memory space that manages the signal and a bitmask
that indicates the specific bits required to control the signal.

Changes in v3:
- replace renesas,sysc-signal with renesas,sysc-signals for case where
more than 1 signal should be described with this property
- Geert: due to this I dropped you tag
Changes in v2:
- none; this patch is new
