ARM: fix the standalone programs
The standalone programs do not use the api calls, but rely
directly on u-boot variable gd->jt for the jump table. Commit
fe1378a - "ARM: use r9 for gd" changed the register holding
the address of gd, but the assembly code in the standalone
examples was not updated accordingly. This broke the programs
on ARM relying on the jumptable in the v2013.10 release.
This patch unbricks them by using the correct register.
