This patch enables zoned support for UFS devices.
By applying this patch, a QEMU run can use parameters to configure whether
each LU of each UFS is zoned, and the capacity, size, and max open zones.
Zoned UFS is implemented by referencing ZBC2.

The AioContext must be unlocked before calling blk_co_unref(), because
it takes the AioContext lock internally in blk_unref_bh(), which is
scheduled in the main thread. If we don't unlock, the AioContext is
locked twice and nested event loops such as in bdrv_graph_wrlock() will
deadlock.

pmu_init() register its event checking the pm_event::supported()
handler. For INST_RETIRED, the event is only registered and the
bit enabled in the PMU Common Event Identification register when
icount is enabled as ICOUNT_PRECISE.
PMU events are TCG-only, hardware accelerators handle them
Slightly simplify non-TCG and user emulation code.
This series still adds assertions in ARM INST_RETIRED
PMU events, in order to bypass a linking failure. Better
would be to restrict ARM PMU events to TCG. Left for
another series.
Since v2:
- Have icount_configure() return bool
- Addressed rth's
