conf: Use unified u-boot config for 64-bit targets
...
The rpi_arm64 configuration supports both Raspberry Pi 3 & 4 in 64-bit
mode. Switching to this config is a small step towards supporting a
unified build for these targets.

linux-raspberrypi: Enable use of 'RPI_EXTRA_CONFIG += ...' in local.conf
...
Before this patch, use of RPI_EXTRA_CONFIG += in a local.conf would overwrite
the needed 'arm_64bit=1' defined in the core recipes. The net result would be
a system that did not boot.
This patch fixes the assignment of 'arm_64bit=1' even if RPI_EXTRA_CONFIG
has been set elsewhere.

...
As of late[1], we defaulted to enabling vc4graphics in MACHINE_FEATURES.
Let's cleanup the machine configurations as per this change.

raspberrypi4-64: Remove the 3G RAM limitation
...
The PCIe bounce buffers were ported[1] in the kernel so we can remove
this limitation now.

raspberrypi4-64.conf: Limit RAM to 3G
...
The PCI controller on the Raspberry Pi 4 acts as a DMA controller and can
only address the first 3Gb[1] of the memory space. On 32bit this was
addressed by implementing bouncing buffers[2] but this currently has no
support for arm64. In order to have working USB, as a workaround, we
limit the ram to 3G.
Fixes #446
