Qualcomm Arm64 DeviceTree fixes for v6.10

This marks the PSHOLD node on SC8280XP as reserved, to resolve a
regression where a reset is triggered instead of a clean shutdown. Also
on SC8280XP the touchscreen properties are adjusted to make it properly
described on CRD and make it work on the Lenovo Thinkpad X13s.

Corrects the LLCC definitions on SC8180X and QDU1000 to allow these
drivers and their dependencies to probe.

X1 Elite CRD is given more CMA space, to avoid running out during boot,
as PCIe SMMU is not accessible.  Audio configuration is corrected, on
the same.

SM6115 SDHC is given an IOMMU stream, to avoid access issues.

Lastly the EL2 non-secure physical timer interrupt on SA8775P is
corrected from its previous incorrect value.

Apart from the regular dts fixes for wrong addresses, missing
or wrong properties, this reverts the previous move away from
cd-gpios to the mmc-controller's internal card-detect.
With this change applied, it was reported that boards could not
detect card anymore, so this go reverted of course.

<id>6db1208bf95b4c091897b597c415e11edeab2e2d</id>
<content type='text'>
An unintended consequence of commit 9c573cd31343 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.

The prior intent of the per-architecture limits were:

  arm64: capped at 0x1FF (9 bits), 5 bits effective
  powerpc: uncapped (10 bits), 6 or 7 bits effective
  riscv: uncapped (10 bits), 6 bits effective
  x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
  s390: capped at 0xFF (8 bits), undocumented effective entropy

Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

An unintended consequence of commit 9c573cd31343 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.

The prior intent of the per-architecture limits were:

  arm64: capped at 0x1FF (9 bits), 5 bits effective
  powerpc: uncapped (10 bits), 6 or 7 bits effective
  riscv: uncapped (10 bits), 6 bits effective
  x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
  s390: capped at 0xFF (8 bits), undocumented effective entropy

Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

<title>syscalls: fix compat_sys_io_pgetevents_time64 usage</title>

Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.

This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.

Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.
