dts: usb: stm32: add number of host channels property

faloj · faloj · commit cb811accc6dc · 2024-10-29T22:28:46.000+01:00
Add the "num-host-channels" property to "st,stm32-otghs" and
"st,stm32-otgfs" compatible dts bindings and to dtsi files comprising such
peripheral. Values are taken from AN4879 and from corresponding reference
manual when missing.
