[PATCH] ARM: i.MX: OCOTP: read serial number with correct endianness

[Robert Karszniewicz]

The serial number is stored with the low bytes first, as can be seen in
Linux commit 8267ff89b713 ("ARM: imx: Add serial number support for
i.MX6/7 SoCs").  The same goes for i.MX8M.

Also renamed the macro to the more descriptive name from Linux.

Fixes: c4d9463d969b ("i.MX: Introduce imx_ocotp_read_uid()")
