Revert "Merge branch 'master' into baytrail"

This reverts commit 7511bcf2e6ddc31ee27418487f2d4b7d93bed1e2, reversing
changes made to cd44fa829c5e8255bf623a4b072cf85bb61b3092.

This should get the tree back to the state it was before the errant push.
The history will be ugly because Fedora disallows force pushing (sigh), but
oh well.

-
-ACPI 5.0 introduces _DEP to designate device objects that OSPM should
-assign a higher priority in start ordering due to future operation region
-accesses.
-
-On Asus T100TA, ACPI battery info are read from a I2C slave device via
-I2C operation region. Before I2C operation region handler is installed,
-battery _STA always returns 0. There is a _DEP method of designating
-start order under battery device node.
-
-This patch is to implement _DEP feature to fix battery issue on the Asus T100TA.
-Introducing acpi_dep_list and adding dep_unmet count in the struct
-acpi_device. During ACPI namespace scan, create struct acpi_dep_data for a
-valid pair of master (device pointed to by _DEP)/slave(device with _DEP), record
-master's and slave's ACPI handle in it and put it into acpi_dep_list. The dep_unmet
-count will increase by one if there is a device under its _DEP. Driver's probe() should
-return EPROBE_DEFER when find dep_unmet is larger than 0. When I2C operation
-region handler is installed, remove all struct acpi_dep_data on the acpi_dep_list
-whose master is pointed to I2C host controller and decrease slave's dep_unmet.
-When dep_unmet decreases to 0, all _DEP conditions are met and then do acpi_bus_attach()
-for the device in order to resolve battery _STA issue on the Asus T100TA.
