[U-Boot] [PATCH v2 03/10] tiny-printf: Reorder code to support %p

[Simon Glass]

With a bit of code reordering we can support %p using the existing code
for ulong.

Move the %p code up and adjust the logic accordingly.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Add a new patch to support %p without DEBUG
