 [bsp][stm32] Fix compile failure when using ARM Compiler V6.

avoid to conflicting types for 'uint32_t' error.

already uint32_t is defined at components/libc/compilers/minilibc/stdint.h.

there is two ways to solve, using <stdint.h>/uint32_t pair or
<rtthread.h>/rt_uint32_t pair.

I choose former because this code belongs to C compiler, not RT-Thread system.
