soc: sifive: ccache: reduce printing on init

Browse source 
The driver prints out 6 lines on startup, which can easily be redcued
to two lines without losing any information.

Note, to make the types work better, uint64_t has been replaced with
ULL to make the unsigned long long match the format in the print
statement.
