stand/uboot: setup archsw before probing devices

Browse Source 
In some cases ubldr would try to mount a disk device before
the archsw struct was filled with functions pointers.
This would result in a NULL pointer derefrence of the arch_getdev field.
Fix that filling the archsw functions earlier.
Note that this matches the EFI behavoiur.
