remove the usage of IRQ_TYPE_NONE to fix loud warnings from
patch (83a86fbb5b56b "irqchip/gic: Loudly complain about
the use of IRQ_TYPE_NONE").

The same was done in commit 242579dd0829 ("arm64: dts: msm8996: fix gic_irq_domain_translate warnings") and commit c16e78b8e862("arm64: dts: msm8916: fix gic_irq_domain_translate warnings") upstream, so fix the same issue in our forward-ported Qualcomm BSP code.

Fix:

Apply the attached patch and recompile

How to test:

Boot the patched kernel and check for the above WARNING in dmesg

Regression potential:

None, it's mechanical modification to silence a WARNING

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-cosmic' to 'verification-done-cosmic'. If the problem still exists, change the tag 'verification-needed-cosmic' to 'verification-failed-cosmic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
