UBUNTU: SAUCE: hack: efi/libstub: mitigate t14s exit_boot_services() failure

BugLink: https://bugs.launchpad.net/bugs/2100858

The UEFI firmware on the Lenovo ThinkPad T14s is broken and
ExitBootServices() often fails and prevents the kernel from starting:

 EFI stub: Exiting boot services...
 EFI stub: Exit boot services failed.

One bootloader entry may fail to start almost consistently (once in a
while it may start), while a second entry may always work even when the
kernel, dtb and initramfs images are copies of the failing entry on the
same ESP.

This can be worked around by starting and exiting a UEFI shell from the
bootloader or by starting the bootloader manually via the Boot Menu
(F12) before starting the kernel.

Notably starting the kernel automatically from the shell startup.nsh
does not work, while calling the same script manually works.

Experiments have revealed that allocating an event before calling
ExitBootServices() can make the call succeed. When providing a
notification function there apparently is no need to actually signal the
event group and CloseEvent() could also be called directly.

Loading the initramfs and dtb from the EFI stub (using the 'initrd' and
'dtb' kernel parameters) instead of from the bootloader can also reduce
the chances of hitting this bug.

drm/msm/dp: Add support for LTTPR handling

Link Training Tunable PHY Repeaters (LTTPRs) are defined in DisplayPort
1.4a specification. As the name suggests, these PHY repeaters are
capable of adjusting their output for link training purposes.

According to the DisplayPort standard, LTTPRs have two operating
modes:
 - non-transparent - it replies to DPCD LTTPR field specific AUX
   requests, while passes through all other AUX requests
 - transparent - it passes through all AUX requests.

Switching between this two modes is done by the DPTX by issuing
an AUX write to the DPCD PHY_REPEATER_MODE register.

The msm DP driver is currently lacking any handling of LTTPRs.
This means that if at least one LTTPR is found between DPTX and DPRX,
the link training would fail if that LTTPR was not already configured
in transparent mode.

The section 3.6.6.1 from the DisplayPort v2.0 specification mandates
that before link training with the LTTPR is started, the DPTX may place
the LTTPR in non-transparent mode by first switching to transparent mode
and then to non-transparent mode. This operation seems to be needed only
on first link training and doesn't need to be done again until device is
unplugged.

It has been observed on a few X Elite-based platforms which have
such LTTPRs in their board design that the DPTX needs to follow the
procedure described above in order for the link training to be successful.

So add support for reading the LTTPR DPCD caps to figure out the number
of such LTTPRs first. Then, for platforms (or Type-C dongles) that have
at least one such an LTTPR, set its operation mode to transparent mode
first and then to non-transparent, just like the mentioned section of
the specification mandates.

arm64: dts: qcom: x1e80100: enable rtc

On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which a
driver can take into account.

On X1E based Windows on Arm machines the offset is stored in a Qualcomm
specific UEFI variable.

Unlike on previous platforms the alarm registers are also unaccessible
on X1E as they are owned by the ADSP.

Assume all X1E machines use similar firmware and enable the RTC in the
PMIC dtsi for now.

Based on a patch by Jonathan Marek. [1]

drm/msm/dpu: fix x1e80100 intf_6 underrun/vsync interrupt

The IRQ indexes for the intf_6 underrun/vsync interrupts are currently
swapped. DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun
interrupt and DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.

This causes timeout errors when using the DP2 controllers, e.g.
