bcm, bcm64: dancing to the drum of the linux clowns for device tree memory size detection (thanks kenji)
looks like linux changed the device tree names for
the memory node:
https://github.com/raspberrypi/linux/commit/4b17654f51fd87c42cda3217b0863e6aa1df49b9#diff-ac03c9402b807c11d42edc9e8d03dfc7
this fixes the memory size detection with latest firmware
on raspberry pi4-b (4GB) for kenji.
