With the change to dma_addr_t from u32 to u64 for the R5 SPL, the
existing typecasts from void* to int or vice-versa cause the compiler to
throw a "cast from pointer to integer of different size".
is this some compiler specific ?. Please mention that
I don't see this warning
https://gist.github.com/uditkumarti/1c4238a7101d97cdc57b7a40d10147d2
I am on gcc version 11.3.1 20220712 (Arm GNU Toolchain 11.3.Rel1)
Therefore this patch changes the casts to a uintptr_t which is
guaranteed to hold any pointer value, thus supressing the compiler
warning.
