libpayload: Use the same type for 32 bit data in readl as in uint32_t.

Browse Source 
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.
