Every Qualcomm SoC physically has a "CRYPTO0<->DDR" interconnect lane.
Allow this property to be present, no matter the SoC.

IPQ5018 has SDI (Secure Debug Image) enabled by TZ by default, and that
means that WDT being asserted or just trying to reboot will hang the board
in the debug mode and only pulling the power and repowering will help.
Some IPQ4019 boards like Google WiFI have it enabled as well.
So, lets add a boolean property to indicate that SDI is enabled by default
and thus needs to be disabled by the kernel.

* Added or improved SoC driver support for Tegra234, Exynos4121, RK3588,
as well as multiple Mediatek and Qualcomm chips
* SCMI firmware gains support for multiple SMC/HVC transport and version
3.2 of the protocol
* Cleanups amd minor changes for the reset controller, memory controller,

Trogdor devices use firmware backed by TF-A instead of Qualcomm's
normal TZ. On TF-A we end up mapping memory as cacheable. Specifically,
you can see in Trogdor's TF-A code [1] in qti_sip_mem_assign() that we
call qti_mmap_add_dynamic_region() with MT_RO_DATA. This translates
down to MT_MEMORY instead of MT_NON_CACHEABLE or MT_DEVICE.
Let's allow devices like trogdor to be described properly by allowing
"dma-coherent" in the SCM node.

Document the compatible for Qualcomm SM6375 SCM.
SCM consumes a single clock (core / RPM_SMD_CE1_CLK), though it does
not matter whether Linux enables it, as one of the billion levels of
firmware ensures it's on anyway. Still, mark it as used for the sake
of correctness.
