ANDROID: suppress FRAME_WARN if IOMMU_IO_PGTABLE_LPAE_SELFTEST

Kernelci allmodconfig tests fail for 32-bit because
the arm_lpae_do_selftests exceeds the stack size. Increase
the expected stack frame size if that test is enabled.

    stack frame size (1184) exceeds limit (1024) in 'arm_lpae_do_selftests' [-Werror,-Wframe-larger-than] in drivers/iommu/io-pgtable-arm.o

To suppress, set the max frame size to 2048 for io-pgtable-arm.o
