iommu/io-pgtable-arm: dynamically allocate selftest device struct
In general a 'struct device' is way too large to be put on the kernel
stack. Apparently something just caused it to grow a slightly larger,
which pushed the arm_lpae_do_selftests() function over the warning
limit in some configurations:
drivers/iommu/io-pgtable-arm.c:1423:19: error: stack frame size (1032) exceeds limit (1024) in 'arm_lpae_do_selftests' [-Werror,-Wframe-larger-than]
1423 | static int __init arm_lpae_do_selftests(void)
| ^
Change the function to use a dynamically allocated faux_device
instead of the on-stack device structure.
Fixes: ca25ec247aad ("iommu/io-pgtable-arm: Remove iommu_dev==NULL special case")
