The Lenovo Yoga 300 laptop's firmware advertises that it provides the _BIX
the method to retrieve battery information. Unfortunately (some versions
of?) the implementation return with an error.

[   21.712228] ACPI Exception: AE_AML_PACKAGE_LIMIT, Index (0x000000010) is beyond end of object (length 0xD) (20160422/exoparg2-427)
[   21.712244] ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.H_EC.BAT1._BIX] (Node ffff95f8ff0b20f0), AE_AML_PACKAGE_LIMIT (20160422/psparse-542)

The _BIF method does succeed and returns convincing data. We detect _BIX
failing and automatically retry with _BIF.
