hw/rtc/twl92230: Silence warnings about missing fallthrough statements 

When compiling with -Werror=implicit-fallthrough, gcc complains about
missing fallthrough annotations in this file. Looking at the code,
the fallthrough is indeed wanted here, but instead of adding the
annotations, it can be done more efficiently by simply calculating
the offset with a subtraction instead of increasing a local variable
one by one.
