u-boot-2019.07: Fix for Raspberry Pi 4

Following recent changes in the BSP the recipe for u-boot 2019.07
was failing to build for Raspberry Pi 4. This fix brings existing
patches from master branch of meta-raspberrypi to AGL which is
still based on Yocto project release Thud.

+Subject: [PATCH 1/7] configs: rpi4: Add defconfigs for rpi4 (32/64)
+
+This defines a minimum defconfig for each of the two Raspberry Pi 4
+variants. One notable difference is that we don't have a embedded dt for
+this board given that the fw supplies us with one which we can reuse.
+Furthermore, the ram size is not queryable through mbox interface as the
+maximum reported size is 1G. The fw patches the dt with the right
+memory configuration and uboot uses it as it is. We avoid u-boot
+touching this configuration by making sure CONFIG_ARCH_FIXUP_FDT_MEMORY
+is deactivated.

+
+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.

+Be aware of the current limitation in firmware which requires an
