ACPI: utils: Dynamically determine acpi_handle_list size

ACPI: utils: Dynamically determine acpi_handle_list size

Address a long-standing "TBD" comment in the ACPI headers regarding the
number of handles in struct acpi_handle_list.

The number 10, which along with the comment dates back to 2.4.23, seems
like it may have been arbitrarily chosen and isn't sufficient in all
cases [1].

Finally change the code to dynamically determine the size of the handles
table in struct acpi_handle_list and allocate it accordingly.

Update the users of to struct acpi_handle_list to take the additional
dynamic allocation into account.
