Subject: [PATCH] pinctrl: at91-pio4: use %pr format string for resource

resource_size_t may be defined as 32 or 64 bit depending on configuration,
so it cannot be printed using the normal format strings, as gcc correctly
warns:

pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':
pinctrl-at91-pio4.c:1003:41: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]
   dev_dbg(dev, "bank %i: hwirq=%u\n", i, res->start);

This changes the format string to use the special "%pr" format
string that prints a resource, and changes the arguments so we
the resource structure directly. I'm also swapping out the arguments
to match the text in the format string.
