This is not a problem for 12-CURRENT as EFI boot works but it doesn't

While here some board arm_install_uboot also copy ubldr.bin et create
firstboot files but it's already done in arm_install_boot

ubldr is the non-pie version of ubldr.bin, do not install two

in the future.
All the u-boot ports know how to load ubldr.bin
