Remove redundant (and incorrect) reserved memory
definition for VideoCore memory. The reserved
memory area is defined in 'overlay-rpi4.dts'.

kernel,bcm2711: Fix RPI4 address mapping
Fix build error and warnings by removing GPIO mapping
from overlay. Also as a note, don't add 'serial1' or 'ethernet'
here, because 'serial1' is already mapped to sel4 kernel by
'chosen' block in 'overlay-rpi4.dts', and the translation for
the 'ethernet' is done with 'ranges' property.

kernel,bcm2711: Fix memory area overlay DTS
First fix is to change the memory area reserved for
the VideoCore from 64 -> 76 MB, as this is the default
value on RPi4. Using other values would require configuration
of the first stage bootloader with 'config.txt' file.
Second fix is separating the disjunct memory areas
to separate nodes, as the generator Python scripts
in 'kernel/tools/' etc discarded the first area below
1GB limit if all areas were defined in the same node.
The effect of different variations can be observed
during kernel build in the generated
'kernel/gen_headers/plat/machine/devices_gen.h' header.
Third fix is adding the reserved memory area for the
VideoCore memory to avoid any collisions.
