platform/x86: x86-android-tablets: Fix Lenovo Yoga Tablet 2 830/1050 poweroff again
Commit 98f30d0ecf79 ("ACPI: power: Switch to sys-off handler API")
switched the ACPI sleep code from directly setting the old global
pm_power_off handler to using the new register_sys_off_handler()
mechanism with a priority of SYS_OFF_PRIO_FIRMWARE.
This is a problem in special cases where the old global pm_power_off
handler later gets overwritten, such as the Lenovo Tab2 poweroff bugfix
in x86-android-tablets. The old global pm_power_off handler gets run
with a priority of SYS_OFF_PRIO_DEFAULT which is lower then
SYS_OFF_PRIO_FIRMWARE, causing the troublesome ACPI poweroff (which
freezes the system) to run first.
Switch the registering of lenovo_yoga_tab2_830_1050_power_off over to
register_sys_off_handler() with a priority of SYS_OFF_PRIO_FIRMWARE + 1
so that it will run before acpi_power_off() to fix this.
