c1ca312a6f hw/rtc/ls7a_rtc: Drop unused inline functions
Remove toy_val_to_time_mon and toy_val_to_time_year as unused,
to avoid a build failure with clang.  Remove all of the other
inline markers too so that this does not creep back in.

4f2c65877c hw/rtc/ls7a_rtc: Fix uninitialied bugs and toymatch writing function
1. Initialize the tm struct in toymatch_write() and ls7a_toy_start() to
   fix uninitialized bugs.
2. Fix toymatch_val_to_time function. By the document, when we calculate
   the expiration year, we should first get current year, and replace the
   0-5 bits with toymatch's 26-31 bits.

Fixes: Coverity CID 1489766, 1489763
