Bug description:
[Impact]
ACPI TAD doesn't really work on several systems. When accessing TAD
interface via sysfs, like setting/getting realtime, it also causes
errors:
[ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39)
[SystemCMOS] (20230331/evregion-130)
[ 478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler
(20230331/exfldio-261)
[ 478.255461] Initialized Local Variables for Method [_GRT]:
[ 478.255461] Local1: 00000000f182542c <Obj> Integer
0000000000000000
[ 478.255464] No Arguments are initialized for method [_GRT]
[ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous
error (AE_NOT_EXIST) (20230331/psparse-529)
[Fix]
Let the driver to install a handler for its SystemCMOS region.
The spec on whether certain devices can use SystemCMOS or not is quite
vague, so follow the de facto implementation, Windows :)
[Test]
Once the patch is applied, setting and getting realtime through TAD
sysfs work, and there's no more error in dmesg.
[Where problems could occur]
Now ACPI TAD driver also depends on ACPI RTC driver, so the memory usage
will go up slightly.
