thinkpad_acpi expects a SSMS method to turn on/off the mute LED
and a MMTS method to turn on/off the microphone mute LED. With
these methods implemented the driver can correctly sync the LEDs
with the corresponding statuses.
There seems to be two different bits to mute the audio in the
Lenovo H8 EC:
* AMUT, used internally (for example to disable the audio before
entering S3).
* ALMT, controllable by the OS, which also toggles the mute LED
(if present).
Tested on a X220T and on a X201.

Currently, the USB ports are still powered during S3, so turning
them off may reduce the power consumption.
Note that, when the USB Always on feature is enabled, the USB
ports are always powered, regardless of the USBP state.
This patch also disables the audio, as it might consume some
power or generate some noise.
Both the USB power and the audio are reenabled by coreboot during
the poweron.

According to USB 2.0 Spec Table 7-7, the High-speed squelch
detection threshold Min 100mV and Max 150mV, and we set USB
2.0 PHY0 and PHY1 squelch detection threshold to 150mV by
default, so if the amplitude of differential voltage envelope
is < 150 mV, the USB 2.0 PHYs envelope detector will indicate
it as squelch.
On Kevin board, if we connect usb device with Samsung U2 cable,
we can see that the impedance of U2 cable is too big according
to the eye-diagram test report, and this cause serious signal
attenuation at the end of receiver, the amplitude of differential
voltage falls below 150mV.

The magic numbers (IOBP SECRT88 and DTLE) for ports 2 and 3 were only
guessed by looking at ports 0 and 1 and extrapolating from there.
Port 3 has been tested (DTLE setting on Librem 13) and confirmed to work

Adding spi_xfer_two_vectors as .xfer_vector for ipq40xx spi_ctrlr.
Commit c2973d196d ("UPSTREAM: spi: Get rid of SPI_ATOMIC_SEQUENCING")
has added a new driver method xfer_vector to support combined write-read
operation within a single CS cycle. The method is wrapped in the
spi_xfer_vector() API. When spi_ctrlr structure does not have
xfer_vector method, API calls write and read operations sequentially.
However the QCA40xx SPI driver has "forced" CS activation-inactivation
in xfer method, so individual operation will break CS after write
operation, making combined write-read cycle broken.
Adding xfer_vector method to spi_ctrlr is a simple fix to prevent this.
