This is incompatible with legacy BIOS ACPI code
where PCNF ACPI method reads this field 32 times.
To make pci_read mmio callback compatible with legacy

PIIX created a made-up value for the UP register since it was read by
guest 32 times for each interrupt.
There's no reason to do this for the new PCIHP: register is only read
once for each interrupt, so clean up code by making read act as an
interrupt acknowledgement: the new UP register clear on read.
In this way we cut down the number of bus rescans
by a factor of 32, and drop a bunch of code that's
now unused.

The ae2810c4bb patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).
This fixes hpratio!=1 case to fall back to the slow path.
