u-boot: Update patches for RPi4ag/rpi4-uboot-update

After a review in upstream, some of the patches were modified. Most
notable changes:
1. use directly the dtb passed by the firmware and make sure uboot
doesn't tweak memory/reg
2. remove known unimplemented support (usb, eth etc.)
3. drop patches that are not needed anymore with the new firmware update
(for example 0012-bcm283x-mbox-Correctly-wait-for-space-to-send.patch)

+Subject: [PATCH 2/7] ARM: bcm283x: Add BCM283x_BASE define
+
+Devices of bcm283x have different base address, depending if they are on
+bcm2835 or bcm2836/7. Use BCM283x_BASE depending on the SoC you want to
+build and only add the offset in the header files.
