hd-geometry: Compute BIOS CHS translation in one place

Currently, it is split between hd_geometry_guess() and
pc_cmos_init_late(). Confusing. info qtree shows the result of the
former. Also confusing.

block: Geometry and translation hints are now useless, purge them

There are two producers of these hints: drive_init() on behalf of
-drive, and hd_geometry_guess().

The only consumer of the hint is hd_geometry_guess().

Remove useless device dependency of HAS_AUDIO

System architecture dictates whether HAS_AUDIO is defined. It's then
useless to check for HAS_AUDIO in files which are only used on those
architectures which always have audio.

Currently HPET ACPI table is created regardless of whether qemu actually

hpet/rtc: Rework RTC IRQ replacement by HPET

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push
routing to IRQ8 completely into the HPET. This allows to turn
hpet_in_legacy_mode() into a private function. Furthermore, this stops
the RTC from clearing IRQ8 even if the HPET is in control....

Register the HPET as a sysbus device and create it that way. As it can
