Alexander von Gluck IV b24dbf95d0 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)
