Now that flags are handled on a fine-grained per-page basis this global
flag is redundant and has a confusing overlap with the pfn_flags_mask and
default_flags.

Most places that return an error code, like -EFAULT, do not set
HMM_PFN_ERROR, only two places do this.
Resolve this inconsistency by never setting the pfns on an error
exit. This doesn't seem like a worthwhile thing to do anyhow.
If for some reason it becomes important,

Add wled_cabc_config, wled_sync_toggle, wled_ovp_fault_status
and wled_ovp_delay callback functions to prepare the driver for
adding WLED5 support.
wled_cabc_config() ===> Used to configure the cabc register.
It is applicable for wled4 and wled5.
wled_sync_toggle() ===>

Add support for WLED5 peripheral that is present on PM8150L PMICs.
PM8150L WLED supports the following:
- Two modulators and each sink can use any of the modulator
- Multiple CABC selection options from which one can be selected/enabled
- Multiple
Convert the qcom-wled bindings from .txt to .yaml format.

The checking boils down to some racy check if the pagemap is still
available or not. Instead of checking this, rely entirely on the
notifiers, if a pagemap is destroyed then all pages that belong to it must
be removed from the tables and the notifiers triggered.
Remove unneeded #if/#endif guards for checking whether the
CONFIG_DEBUG_FS option is set or not. If the option is not set, the
compiler optimizes the functions making the guards
unnecessary.

The pagewalker does not call most ops with NULL vma, those are all routed
to pte_hole instead.
Thus hmm_vma_fault() is only called with a NULL vma from
hmm_vma_walk_hole(), so hoist the check to there.
Now it is clear that snapshotting with no vma is a HMM_PFN_ERROR as

This is v2 of the first simple series with a few additional patches of little
adjustments.
This needs an additional patch to the hmm tester:

Calls to dma_map_sg may return segments / entries than requested
if they fall on page bounderies. The old implementation did not
support this use case.
