It communicates internally over i2c (two of them) , to whatever (RP1 probably)
Yes, it's in the PMIC.

if you want something more realtime, then abusing the PIO or cortex-m3 on the RP1 would be better
so, you need to start by explaining what your actual goal is?
Using a system call (IMHO) just adds overhead.
gettimeofday is also a special case, its not a syscall on most arches, vdso lets userland read the time without that overhead
