bcm4908: use accepted 5.13 DTS patches

Some patches were slightly cleaned up. One things worth mentioning is
that adding:
phy-mode = "rgmii"
broke SF2 driver. It made it access random register breaking switch
setup.

That's why this commit also adds a quick sf2 fix.

+Subject: [PATCH] arm64: dts: broadcom: bcm4908: describe USB PHY
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+BCM4908 uses slightly modified STB family USB PHY. It handles OHCI/EHCI
+and XHCI. It requires powering up using the PMB.
