ARM: dts: k3-j7200-common-proc-board-u-boot: Fix broken ethernet

Since commit 6239cc8c ("arm: dts: k3-j7200: Sync Linux v5.11-rc6 dts
into U-Boot") ranges have been added to CPSW node which results in
U-Boot CPSW driver failing to acquire phy_gmii_sel register range and
thus failing to configure GMII mode correctly.

Fix this by deleting ranges in -u-boot-dtsi just like its done for other
K3 platforms.
