Qualcomm driver updates for v6.20

Support multiple wait queues in the SCM firmware interface and provide
discovery of the wait queue interrupt to deal with the cases where
bootloader didn't patch the DeviceTree with the IRQ information.

Refactor the MDT loader and the SCM driver's peripheral authentication
service interface and introduce support for passing a remoteproc
resource table to the firmware. The remoteproc patches that uses this
and uses this to configure the IOMMU are included here due to
bidirectional dependencies. The end result is remoteproc support on the
Glymur platform.

Enable QSEECOM and thereby UEFI variable access, on the Surface Pro 11.

Make the QMI interface endianness aware, to support ath1Xk on big endian
machines.

Add the Glymur support in LLCC driver.
