dax/cxl: Fix HMEM dependencies

The expectation is that DEV_DAX_HMEM=y should be disallowed if any of
CXL_ACPI, or CXL_PCI are set =m. Also DEV_DAX_CXL=y should be disallowed if
DEV_DAX_HMEM=m. Use "$config || !$config" syntax for each dependency.
Otherwise, the invalid DEV_DAX_HMEM=m && DEV_DAX_CXL=y configuration is
allowed.

Lastly, dax_hmem depends on the availability of the
cxl_region_contains_resource() symbol published by the cxl_core.ko module.
So, also prevent DEV_DAX_HMEM from being built-in when the cxl_core module
is not built-in.

dax: add fsdev.c driver for fs-dax on character dax

The new fsdev driver provides pages/folios initialized compatibly with
fsdax - normal rather than devdax-style refcounting, and starting out
with order-0 folios.

When fsdev binds to a daxdev, it is usually (always?) switching from the
devdax mode (device.c), which pre-initializes compound folios according
to its alignment. Fsdev uses fsdev_clear_folio_state() to switch the
folios into a fsdax-compatible state.

A side effect of this is that raw mmap doesn't (can't?) work on an fsdev
dax instance. Accordingly, The fsdev driver does not provide raw mmap -
devices must be put in 'devdax' mode (drivers/dax/device.c) to get raw
mmap capability.

In this commit is just the framework, which remaps pages/folios compatibly
with fsdax.

Enabling dax changes:

- bus.h: add DAXDRV_FSDEV_TYPE driver type
- bus.c: allow DAXDRV_FSDEV_TYPE drivers to bind to daxdevs
- dax.h: prototype inode_dax(), which fsdev needs

dax/hmem: Request cxl_acpi and cxl_pci before walking Soft Reserved ranges

Ensure cxl_acpi has published CXL Window resources before HMEM walks Soft
Reserved ranges.

Replace MODULE_SOFTDEP("pre: cxl_acpi") with an explicit, synchronous
request_module("cxl_acpi"). MODULE_SOFTDEP() only guarantees eventual
loading, it does not enforce that the dependency has finished init
before the current module runs. This can cause HMEM to start before
cxl_acpi has populated the resource tree, breaking detection of overlaps
between Soft Reserved and CXL Windows.

Also, request cxl_pci before HMEM walks Soft Reserved ranges. Unlike
cxl_acpi, cxl_pci attach is asynchronous and creates dependent devices
that trigger further module loads. Asynchronous probe flushing
(wait_for_device_probe()) is added later in the series in a deferred
context before HMEM makes ownership decisions for Soft Reserved ranges.

Add an additional explicit Kconfig ordering so that CXL_ACPI and CXL_PCI
must be initialized before DEV_DAX_HMEM. This prevents HMEM from consuming
Soft Reserved ranges before CXL drivers have had a chance to claim them.
