software/bios/boot: Fix cast to pointer from integer of different size warnings 

On 64-bit:

    litex/soc/software/bios/boot.c: In function 'serialboot':
    litex/soc/software/bios/boot.c:216:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
	 writepointer = (char *) get_uint32(&frame.payload[0]);
			^

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

Note that using a 32-bit integer is OK, even on 64-bit, as this is
specified by the boot protocol.
