hw/sd: sd: Move the sd_block_{read, write} and macros ahead

Git-commit: ce6ea2efc5fb308ebf11339276f60215fe0ec44c
References: bsc#1175144, CVE-2020-17380, bsc#1176681, CVE-2020-25085
References: bsc#1182282, CVE-2021-3409

These APIs and macros may be referenced by functions that are
currently before them. Move them ahead a little bit.
