Commit 99e1c1137b6f "hw/i386/pc: Populate RTC attribute directly" made linking
the "rtc_state" property unnecessary and removed it. Commit 84e945aad2d0 "vl,
pc: turn -no-fd-bootchk into a machine property" accidently reintroduced the
link. Remove it again since it is not needed.

Fixes: 84e945aad2d0 "vl, pc: turn -no-fd-bootchk into a machine property"

Ah, I did wonder when I was working with this code whether that
rtc_state link was really necessary.

We could now remove the rtc argument from the pc_cmos_init()
function, because we can guarantee that it's in x86ms->rtc,
which the function already has access to from its pcms argument.

thanks

This series goes one step further and inlines this function. It would be a nice to get some feedback before the freeze.

Best regards,
