allwinner: uboot: make consistent use of r_i2c across all stages from bootloader to kernel

In sunxi-6.1 and sunxi-6.5 kernel we have a patch that changes r_rsb to r_i2c. But same
change is not done for u-boot. Mixing use of r_rsb and r_i2c seems to cause issues if
its also something handled in crust. Hence making it consistent across u-boot and kernel
dts files

+Subject: [PATCH 170/170] arm64: dts: sun50i-h6-orangepi.dtsi: Rollback r_rsb
+ to r_i2c
+
+This fix affects two boards:
+sun50i-h6-orangepi-lite2.dts
+sun50i-h6-orangepi-one-plus.dts
+
+It also depends on the revision of the board.
+If your board fails when working with this fix, just disable
+it by adding (-) minus to the first position of the line
+in which the patch is written in the series.conf file.
