net: dsa: sja1105: Replace sja1105_spi_send_int with sja1105_xfer_{u32, u64}
Having a function that takes a variable number of unpacked bytes which it generically calls an "int" is confusing and makes auditing patches next to impossible. We only use spi_send_int with the int sizes of 32 and 64 bits. So just make the spi_send_int function less generic and replace it with the appropriate two explicit functions, which can now type-check the int pointer type. Note that there is still a small weirdness in the u32 function, which has to convert it to a u64 temporary. This is because of how the packing API works at the moment, but the weirdness is at least hidden from callers of sja1105_xfer_u32 now. Suggested-by: David S.
