gpiolib: use correct format specifier for ptrdiff_t
C99 specifies the 't' length modifier type for pointer difference.
barebox vsnprintf supports it, thus use it.
We are guaranteed sizeof(long) == sizeof(void *) in barebox, so this
doesn't make a difference in practice except that it silences
following GCC warning:
./drivers/gpio/gpiolib.c: In function 'gpioinfo_request':
./include/printk.h:77:43: warning: format '%ld' expects argument of
type 'long int', but argument 3 has type 'int' [-Wformat=]
...
./barebox-stm32/drivers/gpio/gpiolib.c:89:3: note: in expansion of macro 'pr_err'
89 | pr_err("_gpio_request: gpio-%ld (%s) status %d\n",
