9de5b89e4c rpi4: enable dram bank initialization
When booting through the efi stub, the memory map get's created by
reading the dram bank information. Depending on the version of the RPi4
this information changes. Read the device tree to initialize the dram
bank data structure. This way the kernel is able to access the whole
range of available memory.

193279d784 RPI: 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.
