It depends on Marwell so group it together.

While there, split out Cenatek, Micron generic chipset support to their own

remove few unused ATA_AHCI_P_CMD_* defines.

Futher reduce differences with FreeBSD r183724:
* add ata_netcell_setmode() instead of relying on ata_generic_chipinit()
* add ata_promise_mio_setprd() for promise
* prepare siliconimage for port multipliers

In preparations for pseudo-modularization.

kernel - Fix boot-time panic in NATA revealed by new callout mechanics

* The NATA driver was using spin locks in a very, very dangerous way.
They did not play nice with the new blocking callout mechanism.

* Replace all of NATAs spinlocks with lockmgr locks. In addition, change
all asynchronous callout_stop() calls to synchronous callout_stop_sync()
calls, and use callout_init_lk() to auto-lock ch->state_lock for the
callback, which fixes a long-time deadlock race.

resource: Per-CPU hardware resources support, step 3 of many

- Add cpuid parameter to bus_set_resource() and bus_set_resource
DEVMETHOD; Pass this parameter to resource_list_add()
- Obtain interrupt resource's owner CPU, i.e. target CPU, from
MachIntrABI and pass it to bus_set_resource(), so that the owner
CPU of the interrupt resource could be correctly setup
- Rest of types of resources, e.g. IOPORT, MEMORY and DRQ, are
shared across CPUs, so their cpuids are set to -1

Scanning PCI configuration registers (which are not going to change) on
