The restriction on UHS-I speed modes was added to all SM8550 platforms
by copying it from SM8450 dtsi file, and due to the overclocking of SD
cards it was an actually reproducible problem. Since the latter issue
has been fixed, UHS-I speed modes are working fine on SM8550 boards,
below is the test performed on SM8550-HDK:
SDR50 speed mode:

Unset the UHS-I speed mode restrictions from the SM8550 platform dtsi
file, there is no indication that the SDHC controller is broken.

The reported problem of some non-working UHS-I speed modes on SM8450
originates in commit 0a631a36f724 ("arm64: dts: qcom: Add device tree
for Sony Xperia 1 IV"), and then it was spread to all SM8450 powered
platforms by commit 9d561dc4e5cc ("arm64: dts: qcom: sm8450: disable
SDHCI SDR104/SDR50 on all boards").
The tests show that the rootcause of the problem was related to an
overclocking of SD cards, and it's fixed later on by commit a27ac3806b0a
("clk: qcom: gcc-sm8450: Use floor ops for SDCC RCGs").
Since then both SDR50 and SDR104 speed modes are working fine on SM8450,

arm64: dts: qcom: hamoa: Add EL2 overlay for hamoa-evk
Add support for building an EL2 combined DTB for the hamoa-evk
in the Qualcomm DTS Makefile.
The new hamoa-iot-evk-el2.dtb is generated by combining the base
hamoa-iot-evk.dtb with the x1-el2.dtbo overlay, enabling EL2-specific
configurations required by the platform.

arm64: dts: qcom: talos: Add missing clock-names to GCC
The binding for this clock controller requires that clock-names are
present. They're not really used by the kernel driver, but they're
marked as required, so someone might have assumed it's done on purpose
(where in reality we try to stay away from that since index-based
references are faster, take up less space and are already widely used)
and referenced it in drivers for another OS.
Hence, do the least painful thing and add the missing entries.
