overlays: pisound: Make button pins owned by card
The pisound overlay claims a number of GPIOs using a pinctrl node, but for some reason hangs this claim on the main gpio node. This obscures the ownership of the pins (as shown by gpioinfo and in the kernel logs) and isn't scalable - only one overlay can use the trick at a time. Change the overlay to make the pin ownership clear and avoid any future conflicts, removing a bogus claim on pins_spi0 at the same time.
