Bug Description
[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.
