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. Signed-off-by: Matthias Brugger <mbrugger@suse.com>
