hw/sd/pl181: Use named GPIOs

To make the code easier to manage/review/use, rename the
cardstatus[0] variable as 'card_readonly' and name the GPIO
"card-read-only".
Similarly with cardstatus[1], renamed as 'card_inserted' and
name its GPIO "card-inserted".

Adapt the users accordingly by using the qdev_init_gpio_out_named()
function.
