Merge: arm64: Update drivers/soc/tegra to v6.0

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/1484

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2135064

Update drivers/soc/tegra to v6.0 level. This includes patches from
drivers/memory/tegra, drivers/firmware/tegra, and drivers/misc/sram.{c,h}
needed by the tegra SoCs.

V4: Added a few new fixes and config change to allow kernel to boot
    on Nvidia Orin (from NVME and without builtin nic support)

V3: Dropped upstream commit 3da9b0f "pwm: tegra: Add runtime
    PM and OPP support" which was merged as part of MR !1708

V2: Dropped a number of patches found in other MRs and added
    dependency on them.  
    Also added a few more tegra soc related patches from upstream.

+        These are pad configuration nodes. On Tegra SoCs a pad is a set of
+        pins which are configured as a group. The pin grouping is a fixed
+        attribute of the hardware. The PMC can be used to set pad power
+        state and signaling voltage. A pad can be either in active or
+        power down mode. The support for power state and signaling voltage
+        configuration varies depending on the pad in question. 3.3 V and
+        1.8 V signaling voltages are supported on pins where software
+        controllable signaling voltage switching is available.
+
+        Pad configurations are described with pin configuration nodes
+        which are placed under the pmc node and they are referred to by
+        the pinctrl client properties. For more information see
+
+          Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
