The kernel object produced by the ipados27 build tree is mach.development.bcm2837.unstripped; the .noctf variant is not emitted. Fix the reference in build-sheng-source-drivers.py and all other scripts that contained the wrong suffix. Also update submodule pointers for Adreno740 (preemption A1) and AdrenoMetal (priority forwarding + pass reporter), and regenerate turnip-gmem-mutable-swap.patch to include the NativeAdrenoAbiPriority method-17 call in tu_knl_darwin.cc.

"""Qualify the generic ArmDTPlatform expert under the real QEMU UEFI/XNU path.

The QEMU fixture supplies actual QEMU virt GICv3 resources and a CHRP NVRAM

proxy around the generic `device-tree` platform root. It says nothing about

sheng hardware. Both observations must show native 4K translation and the real
