ACPI: bus: Add context argument to acpi_dev_install_notify_handler()

Browse Source 
Add void *context arrgument to the list of arguments of
acpi_dev_install_notify_handler() and modify it to pass that argument
as context to acpi_install_notify_handler() instead of its first
argument which is problematic in general (for example, if platform
drivers used it, they would rather get struct platform_device pointers
or pointers to their private data from the context arguments of their
notify handlers).

Make all of the current callers of acpi_dev_install_notify_handler()
take this change into account so as to avoid altering the general
functionality.
