Remove CONFIG_USE_STDINT

You do not need to use the typedefs provided by compiler.

Our compilers are either IPL32 or LP64.  Hence, U-Boot can/should
always use int-ll64.h typedefs like Linux kernel, whatever the
typedefs the compiler internally uses.

-       If stdint.h is available with your toolchain you can define this
-       option to enable it. You can provide option 'USE_STDINT=1' when
-       building U-Boot to enable this.
