gpio / ACPI: Use pin index and bit length
Fix code when the operation region callback is for an gpio, which is not at index 0 and for partial pins in a GPIO definition. For example: Name (GMOD, ResourceTemplate () { //3 Outputs that define the Power mode of the device GpioIo (Exclusive, PullDown, , , , "\\_SB.GPI2") {10, 11, 12} }) } If opregion callback calls is for: - Set pin 10, then address = 0 and bit length = 1 - Set pin 11, then address = 1 and bit length = 1 - Set for both pin 11 and pin 12, then address = 1, bit length = 2 This change requires updated ACPICA gpio operation handler code to send the pin index and bit length.
