[SRU][M][PATCH v6 0/3] Dynamically determine acpi_handle_list size

[Ivan Hu]

BugLink: https://bugs.launchpad.net/bugs/2049733

[Impact]
ACPI handle list will be dynamic allocated without default fixed size.

[Fix]
Currently the ACPI_MAX_HANDLES is defined fix to 10, and it is not enough for
some platforms that called ACPI _PSL method to get passive cooling device
objects. then will get the error message "Invalid passive threshold", this 
patch change the fixed size with the dynamic handle list size which fixes the
handle reference error.

[Test Case]
check the dmesg to see if there is the error message "Invalid passive threshold"

[Where problems could occur]
Only change the fixed size with the dynamic handle list size. Risk of regression
is low.

[Other Info]

and modify the cherrypicked to backported
