hwaccess: add endianness converting deserialization functions
Add functions like
`uint32_t read_le32(const void *base, size_t offset);`
Read a 32 bit unsigned from a base with an offset.
Having prototypes and a macro generated implementation makes it easier
to read, understand and spot errors in one of them.
