Merge branches 'acpi-general', 'acpi-processor', 'acpi-lpss' and 'acpi-battery'

* acpi-general:
  ACPI: use kstrto*() instead of simple_strto*()

* acpi-processor:
  ACPI / processor replace __attribute__((packed)) by __packed

* acpi-lpss:
  ACPI / LPSS: Take I2C host controllers out of reset

* acpi-battery:
  ACPI / battery: add quirk for Acer Aspire V5-573G
  ACPI / battery: use callback for setting up quirks
