[u-boot-test-hooks][PATCH 1/2] bin/writer.rpi_mount: Use kernel= and simplify logic

[Tom Rini]

Rather than guess what we need to name our u-boot.bin file as for it to
boot make use of the kernel= option to always call it u-boot.bin and
then on 64bit platforms (and since future platforms use rpi_arm64 this
list should not grow) also pass in arm_64bit=1.
