raspberrypi*.conf: Remove vc4 configuration as we already default to it
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

raspberrypi4-64.conf: Remove memory limitation
We can do this because the kernel now includes a workaround for the DMA
issue.
