uacce: supports device isolation feature

mainline inclusion
from mainline-v6.3-rc1
commit e3e289fb
category: feature
bugzilla: https://gitee/com/openeuler/kernel/issues/16VW8E
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e3e289fbc0b520cf469469e8cdba84a50424eb65



-------------------------------------------------------------------

UACCE adds the hardware error isolation feature. To improve service
reliability, some uacce devices that frequently encounter hardware
errors are isolated. Therefore, this feature is added.

Users can configure the hardware error threshold by 'isolate_strategy'
sysfs node. The user space can get the device isolated state by 'isolate'
sysfs node. If the number of device errors exceeds the configured error
threshold, the device will be isolated. It means the uacce device is
unavailable.
