struct rtc_time in human readable format.
Instead of open coding that each time introduce %ptR[dt][r] specifier.

Petr, is it now looks good to you? Can you give a tag?

Use %ptR instead of open coded variant to print content of
struct rtc_time in human readable format.
Note, we drop the validation option. This is only used in
a deprecated ABI and is mostly wrong as many RTCs will still be valid
after 2100.
