Provide option to avoid defining a custom version of uintptr_t.
There's a definition in stdint.h (provided by gcc) which will be more correct if available. Define CONFIG_USE_STDINT to use this feature, or USE_STDINT=1 on the 'make' commmand. This adjusts the settings for x86 and sandbox, with both have 64-bit options.

Changed to preserve a clear boundary between stdint and non-stdint Signed-off-by: Simon Glass <sjg@chromium.org>
