lib/logic_iomem: Fix 32-bit build
On a 32-bit build, the (unsigned long long) casts throw warnings
(or errors) due to being to a different integer size. Cast to
uintptr_t first (with the __force for sparse) and then further
to get the consistent print on 32 and 64-bit.
Fixes: ca2e334232b6 ("lib: add iomem emulation (logic_iomem)")
