[PATCH v2] arm64: dts: qcom: hamoa-iot-som: Unreserve GPIOs blocking SPI11 access

[Xueyao An]

GPIOs 44-47 were previously reserved, preventing Linux from accessing
SPI11 (qupv1_se3). Since there is no TZ use case for these pins on Linux,
they can be safely unreserved. Removing them from the reserved list
resolves the SPI11 access issue for Linux.

Please read carefully internal guideline about changelogs and tags.

<form letter>
This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). Tag is
"received", when provided in a message replied to you on the mailing
list. Tools like b4 can help here. However, there's no need to repost
patches *only* to add the tags. The upstream maintainer will do that for
tags received on the version they apply.

Please read:
https://elixir.bootlin.com/linux/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.
</form letter>


Best regards,
Krzysztof

Note: you sent a v2 of the patch, it's expected that you provide
a short changelog and a link to the previous revisions.

Please switch to using the b4 tool, which help you meeting that and
other expectations - check out the internal upstreaming guide
