Dragonboard845c doesn't have board-specific board-id programmed, it uses
generic 0xff. Thus add the property with the 'variant' of the
calibration data.
Note: the driver will check for the calibration data for the following
IDs, so older board-2.bin files that were distributed as a part of
Linaro releases will continue to work.
- 'bus=snoc,qmi-board-id=ff,qmi-chip-id=30214,variant=Thundercomm_DB845C'
- 'bus=snoc,qmi-board-id=ff,qmi-chip-id=30214'
- 'bus=snoc,qmi-board-id=ff'
For the reference, the board is identified by the driver in the
following way:
ath10k_snoc 18800000.wifi: qmi chip_id 0x30214 chip_family 0x4001 board_id 0xff soc_id 0x40030001
ath10k_snoc 18800000.wifi: qmi fw_version 0x2009856b fw_build_timestamp 2018-07-19 12:28 fw_build_id QC_IMAGE_VERSION_STRING=WLAN.HL.2.0-01387-QCAHLSWMTPLZ-1

The property vddp-ref-clk-max-microamp (for VDDP ref clk supply which is
l25 regulator) is not documented in MSM8996 UFS PHY bindings
(qcom,msm8996-qmp-ufs-phy). It is mentioned in the other UFS PHY
bindings for qcom,msm8996-ufs-phy-qmp-14nm.
The MSM8996-based Xiaomi devices configure l25 regulator in a
conflicting way:
1. with maximum 100 uAmp for VDDP ref clk supply of UFS PHY,
2. with maximum 450 mAmp for VCCQ supply of UFS.
Since the vddp-ref-clk-max-microamp property is basically not
documented for that UFS PHY and has a conflicting values, drop it
entirely as it looks like not tested and not used ever.

The SAR node, ap_sar_sensor, needs to be enabled in addition to the i2c
bus it resides on. Let's simplify this by leaving the sensor node
enabled by default while leaving the i2c bus disabled by default. On
boards that use the sensor, we already enable the i2c bus so we can
simply remove the extra bit that enables the sar sensor node. This saves
some lines but is otherwise a non-functional change.

Having these pins with outputs is good on a fresh boot because it puts
the boot and reset pins in a known "good" state. Unfortunately, that
conflicts with the fingerprint firmware flashing code. The firmware
flashing process binds and unbinds the cros-ec and spidev drivers and
that reapplies the pin output values after the flashing code has
overridden the gpio values. This causes a problem because we try to put
the device into bootloader mode, bind the spidev driver and that
inadvertently puts it right back into normal boot mode, breaking the
flashing process.
Fix this by removing the outputs. We'll introduce a binding for
fingerprint cros-ec specifically to set the gpios properly via gpio APIs
during cros-ec driver probe instead.

While scoping signals, we found that the PCIe signals weren't
compliant at bootup. Specifically, the bootloader was setting up PCIe
and leaving it configured, then jumping to the kernel. The kernel was
turning off the regulator while leaving the PCIe clock running, which
was a violation.
In the regulator bindings (and the Linux kernel driver that uses
them), there's currently no way to specify that a GPIO-controlled
regulator should keep its state at bootup. You've got to pick either
"on" or "off". Let's switch it so that the PCIe regulator defaults to
"on" instead of "off". This should be a much safer way to go and
avoids the timing violation. The regulator will still be turned off
later if there are no users.

"A set of x86 fixes and updates:
- Make the prctl() for enabling dynamic XSTATE components correct so
it adds the newly requested feature to the permission bitmap
instead of overwriting it. Add a selftest which validates that.
- Unroll string MMIO for encrypted SEV guests as the hypervisor
cannot emulate it.
- Handle supervisor states correctly in the FPU/XSTATE code so it
takes the feature set of the fpstate buffer into account. The
feature sets can differ between host and guest buffers. Guest
buffers do not contain supervisor states. So far this was not an
issue, but with enabling PASID it needs to be handled in the buffer
offset calculation and in the permission bitmaps.
- Avoid a gazillion of repeated CPUID invocations in by caching the
values early in the FPU/XSTATE code.
- Enable CONFIG_WERROR in x86 defconfig.
- Make the X86 defconfigs more useful by adapting them to Y2022
