ACPI: Add sysfs ABI documentation
Add initial ABI documentation for ACPI devices' sysfs interfaces. Contacts information fields are filled with current ACPI maintainer and the relevant authors are carbon copied.

| 5 | + This attribute indicates the full path of ACPI namespace | |
| 6 | + object associated with the device object. For example, | |
| 7 | + \_SB_.PCI0. | |
| 8 | + This file is not present for device objects representing | |
| 9 | + fixed ACPI hardware features (like power and sleep | |
| 10 | + buttons). | |

| 15 | +Description: | |
| 16 | + This attribute indicates the PNP IDs of the device object. | |
| 17 | + That is acpi:HHHHHHHH:[CCCCCCC:]. Where each HHHHHHHH or | |
| 18 | + CCCCCCCC contains device object's PNPID (_HID or _CID). | |

| 23 | +Description: | |
| 24 | + This attribute indicates the hardware ID (_HID) of the | |
| 25 | + device object. For example, PNP0103. | |
| 26 | + This file is present for device objects having the _HID | |
| 27 | + control method. | |

| 32 | +Description: | |
| 33 | + This attribute contains the output of the device object's | |
| 34 | + _STR control method, if present. | |

| 39 | +Description: | |
| 40 | + This attribute contains the output of the device object's | |
| 41 | + _ADR control method, which is present for ACPI device | |
| 42 | + objects representing devices having standard enumeration | |
| 43 | + algorithms, such as PCI. | |

| 56 | + Writing 1 to this attribute will trigger hot removal of | |
| 57 | + this device object. This file exists for every device | |
| 58 | + object that has _EJ0 method. |
