bootm: Reinstate special case for standalone images
For standalone images, bootm had a special case where the OS boot function was NULL but did actually exist. It was just called manually. This was removed by commit 35fc84fa which checks for the non-existence of this function before the special case is examined. There is no obvious reason why standalone is handled with a special case. Adjust the code so that standalone has a normal OS boot function. We still need a special case for when the function returns, but at least we can avoid the main problem. This is intended to fix the reported: ERROR: booting os 'U-Boot' (17) is not supported but needs testing. Signed-off-by: Simon Glass <sjg@chromium.org>
