software/include/base: Fix size_t, ptrdiff_t, and (u)intptr_t

Browse source 
As per convention, the types of size_t, ptrdiff_t, intptr_t, and
uintptr_t should be based on "long" or "int" depending on the platform
(32-bit or 64-bit).

This fixes compiler warnings of the following type:

    litex/soc/software/liblitesdcard/sdcard.c: In function 'sdcard_read':
    litex/soc/software/liblitesdcard/sdcard.c:476:39: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
      sdblock2mem_dma_base_write((uint64_t)(uintptr_t) buf);
