data: Drop ARM FDT dts from repo

* We depend on FDT passed to the bootloader now
from EFI or u-boot via fdt_addr_r now
* We leave an fdt path within the boot partition
(for now) to allow / encourage users to optionally
plug in their own DTB's for troubleshooting. (only
on u-boot loader)

Avoid adding uboot for ARM64 bootloader

Maybe it will be needed on real hw later.

riscv: Fix build, handle .riscv loader

* We accept the riscv loader to build it, but don't really put it
into the image since for now you'll just want the haiku_loader.riscv
for things like TinyEMU

riscv64/boot: Add same u-boot potential that arm has, drop L_DYNAMIC

* Tianocore is still in an early state for RISCV64 with a lot of work
needed around qemu support.
* u-boot however is working, and can load EFI binaries... so follow the
arm model for now. (EFI via u-boot, or EFI via EFI Bios)

riscv64: Generate a bootable EFI MMC image

* mmc might be not ideal. But raw is just a single partition and
anyboot is heavily x86. MMC will technically work for now to get
bootable images.
* floppyboot isn't used on EFI platforms, since we call two different
actions, just drop floppyboot altogether on EFI SD Images.

* Place haiku_loader.efi at EFI/BOOT/BOOTXXX.EFI
* Generate boot.scr for u-boot + EFI
* haiku-mmc.image now attempts to auto-boot in qemu-system-arm
* Same code paths should roughly apply for arm64,riscv,etc
