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 a mechanical modification to silence a WARNING
