Merge branches 'acpi-numa', 'acpi-glue', 'acpi-config' and 'acpi-pmic'

* acpi-numa:
  ACPI: Add LoongArch support for ACPI_PROCESSOR/ACPI_NUMA

* acpi-glue:
  driver core: Split device_platform_notify()
  software nodes: Split software_node_notify()
  ACPI: glue: Eliminate acpi_platform_notify()
  ACPI: bus: Rename functions to avoid name collision
  ACPI: glue: Change return type of two functions to void
  ACPI: glue: Rearrange acpi_device_notify()

* acpi-config:
  ACPI: configfs: Make get_header() to return error pointer
  ACPI: configfs: Use sysfs_emit() in "show" functions

* acpi-pmic:
  ACPI / PMIC: XPower: optimize MIPI PMIQ sequence I2C-bus accesses
  ACPI / PMIC: XPower: optimize I2C-bus accesses
