The current cppc acpi driver works with only one pcc subspace id.

Move the GET_FIELD and SET_FIELD macros to vas.h as VAS and other
users of VAS, including NX-842 can use those macros.
There is a lot of related code between the VAS/NX kernel drivers
and skiboot. For consistency switch the order of parameters in
SET_FIELD to match the order in skiboot.

Hi Jaegeuk,
I try this patch and find it can fix below case:

The default threshold is set to 64KB, but configurable by sysfs/min_hot_blocks.

So I repost this email again.

Meanwhile, changed the assignment of iovad->cached32_node from rb_next to
rb_prev of &free->node in function __cached_rbnode_delete_update.

I'm not sure whether the compiler can optimize it, but move it out will
be better. At least, it does not require lock protection.

To make sure iovad->cached32_node and iovad->cached64_node can exactly
control dma32 and dma64 area. It also help us to remove the parameter
pfn_32bit of init_iova_domain.
