The margin debugfs node controls the "Enable Margin Test" field of the
lane margining operations. This field selects between either low or high
voltage margin values for voltage margin test or left or right timing
margin values for timing margin test.
According to the USB4 specification, whether or not the "Enable Margin
Test" control applies, depends on the values of the "Independent
High/Low Voltage Margin" or "Independent Left/Right Timing Margin"
capability fields for voltage and timing margin tests respectively. The
pre-existing condition enabled the debugfs node also in the case where
both low/high or left/right margins are returned, which is incorrect.
This change only enables the debugfs node in question, if the specific
required capability values are met.

On an (old) x86 system with SRAT just covering space above 4Gb:
ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0xfffffffff] hotplug
the commit referenced below leads to this NUMA configuration no longer

memblock_validate_numa_coverage() checking for NUMA_NO_NODE (only). This
in turn led to memblock_alloc_range_nid()'s warning about MAX_NUMNODES
triggering, followed by a NULL deref in memmap_init() when trying to
access node 64's (NODE_SHIFT=6) node data.
To compensate said change, make memblock_set_node() warn on and adjust

We'll need to start identifying the platforms independently in display
code in order to break free from the i915 and xe IS_<PLATFORM>()
macros. This is fairly straightforward, as we already identify most
platforms by PCI ID in display probe anyway.
As the first step, add platform descriptors with pointers to display
info. We'll have more platforms than display info, so minimize
duplication:
- Add separate skl/kbl/cfl/cml descriptors while they share the display
info.
- Add separate jsl/ehl descriptors while they share the display info.
Identify ADL-P (and derivatives) and DG2 descriptors by their names even
though their display info is Xe LPD or HPD.
