The previous commit removed the dependencies on the
target-specific TARGET_PAGE_FOO macros. We can now
move vhost-vdpa.c to the 'softmmu_virtio_ss' source
set to build it once for all our targets.

Similarly to commit e414ed2c47 ("virtio-iommu: Use
target-agnostic qemu_target_page_mask"), Replace the
target-specific TARGET_PAGE_SIZE and TARGET_PAGE_MASK
definitions by a call to the runtime qemu_target_page_size()
helper which is target agnostic.

In order to make vhost-vdpa.c a target-agnostic source unit,
we need to remove the TARGET_PAGE_SIZE / TARGET_PAGE_MASK /
TARGET_PAGE_ALIGN uses. TARGET_PAGE_SIZE will be replaced by
the runtime qemu_target_page_size(). The other ones will be
deduced from TARGET_PAGE_SIZE.
Since the 3 macros are used in 3 related functions (sharing
the same call tree), we'll refactor them to only depend on
TARGET_PAGE_MASK.
Having the following call tree:
vhost_vdpa_listener_region_del()
-> vhost_vdpa_listener_skipped_section()
-> vhost_vdpa_section_end()
The first step is to propagate TARGET_PAGE_MASK to
vhost_vdpa_listener_skipped_section().

current code sets PCI_SEC_LATENCY_TIMER to RW, but for
pcie to pcie bridges it must be RO 0 according to
pci express spec which says:
This register does not apply to PCI Express. It must be read-only
and hardwired to 00h. For PCI Express to PCI/PCI-X Bridges, refer to the
[PCIe-to-PCI-PCI-X-Bridge] for requirements for this register.
also, fix typo in comment where it's made writeable - this typo
is likely what prevented us noticing we violate this requirement
in the 1st place.
