These fixes all landed in 6.5-rc2, mantic and noble have them for sure, closing
those tasks.
I'd expect backporting to be done for Lunar and Jammy if necessary.

Bug description:
On ASUS TUF A16 it is reported that the ITE5570 ACPI device connected to
GPIO 7 is causing an interrupt storm. This issue doesn't happen on
Windows.
Comparing the GPIO register configuration between Windows and Linux
bit 20 has been configured as a pull up on Windows, but not on Linux.
Checking GPIO declaration from the firmware it is clear it *should* have
been a pull up on Linux as well.
```
GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0007
}
```
On Linux amd_gpio_set_config() is currently only used for programming
the debounce. Actually the GPIO core calls it with all the arguments
that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`.
To solve this issue expand amd_gpio_set_config() to support the other
arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`,
`PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.
