libpayload: Use the same type for 32 bit data in readl as in uint32_t.
The compiler gets mad when the types are equivalent size but not necessarily interchangeable because of strict aliasing checks. Since uint32_t is likely to be used when trying to read 32 bit data, it makes sense for them to be the compatible.
