litex/soc/software/liblitesdcard/sdcard.c: In function 'sdcard_read':
    litex/soc/software/liblitesdcard/sdcard.c:476:29: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

When casting a pointer (32-bit or 64-bit, depending on the platform) to
a 64-bit integer, an intermediate cast to "uintptr_t" should be used to
avoid warnings like the above.
