Fixes for a few clk drivers and bindings:

- Add a missing property to the Mediatek MT8188 clk binding to
keep binding checks happy

- Avoid an OOB by setting the correct number of parents in
dispmix_csr_clk_dev_data

- Allocate clk_hw structs early in probe to avoid an ordering
issue where clk_parent_data points to an unallocated clk_hw
when the child clk is registered before the parent clk in the
SCMI clk driver

Only select ARCH_WANT_HUGE_PMD_SHARE on 64-bit x86.
Page table sharing requires at least three levels because it involves
shared references to PMD tables; 32-bit x86 has either two-level paging
(without PAE) or three-level paging (with PAE), but even with
three-level paging, having a dedicated PGD entry for hugetlb is only
barely possible (because the PGD only has four entries), and it seems
unlikely anyone's actually using PMD sharing on 32-bit.

Having ARCH_WANT_HUGE_PMD_SHARE enabled on non-PAE 32-bit X86 (which
has 2-level paging) became particularly problematic after commit
59d9094df3d7 ("mm: hugetlb: independent PMD page table shared count"),
since that changes `struct ptdesc` such that the `pt_mm` (for PGDs) and
the `pt_share_count` (for PMDs) share the same union storage - and with
2-level paging, PMDs are PGDs.

(For comparison, arm64 also gates ARCH_WANT_HUGE_PMD_SHARE on the
configuration of page tables such that it is never enabled with 2-level
paging.)

The SCMI clock driver currently assumes that parent clocks are always
initialized before their children. However, this assumption can fail if
a child clock is encountered before its parent during probe.

This leads to an issue during initialization of the parent_data array:

sclk->parent_data[i].hw = hws[sclk->info->parents[i]];

If the parent clock's hardware structure has not been initialized yet,
this assignment results in invalid data.

To resolve this, allocate all struct scmi_clk instances as a contiguous
array at the beginning of the probe and populate the hws[] array
upfront. This ensures that any parent referenced later is already
initialized, regardless of the order in which clocks are processed.

Note that we can no longer free individual scmi_clk instances if
scmi_clk_ops_init() fails which shouldn't be a problem if the SCMI
platform has proper per-agent clock discovery.

pci_msix_write_tph_tag() takes the per device MSI descriptor mutex and then
invokes msi_domain_get_virq(), which takes the same mutex again. That
obviously results in a system hang which is exposed by a softlockup or
lockdep warning.

Move the lock guard after the invocation of msi_domain_get_virq() to fix
this.

AMD Cyan Skillfish (Family 17h, Model 47h, Stepping 0h) has an issue
that causes system oopses and panics when performing TLB flush using
INVLPGB.

However, the problem is that that machine has misconfigured CPUID and
should not report the INVLPGB bit in the first place. So zap the
kernel's representation of the flag so that nothing gets confused.
