busdma - Remove filter functionality
- Remove filtfunc and filtarg arguments from bus_dma_tag_create() and
fix all callers. All callers use NULL today for both filterfunc and
filterarg with one exception: if_jme.
- Remove filter functionality internally and parent tag tracking.
Without filter functions, we do not need to keep track of tag
ancestry. All inheritance of the parent tag's parameters occurs when
creating the new child tag.
- rename run_filter() to addr_needs_bounce().
- FreeBSD keeps the filtfunc and filtarg arguments but requires them to
be NULL.
- Drop filterfunc usage from if_jme.
In case of "JMC260 chip full mask revision 2", which has a hardware bug
when it comes to DMA transfers crossing the 4 GB bounday, the parent
buffer tag already limits DMA memory to 32bit address space. As such it
should be safe to drop the filterfunc. The filterfunc was checking if
the lower 32bits of the physical address used for DMA are all 0. In case
of a 32bit address space, the only address where all lower 32-bits are
all zero is 0 itself and I am here assuming that the physical address 0
is not used for DMA transfers!

The missing M_ZERO was causing kernel data leakage issues.

"Add bunch of PCI IDs of Intel Wildcat Point (9 Series) chipsets."
* Do not import isa, macio, sbus and usb drivers
* snd_au88x0 has been removed. According to the FreeBSD commit message, it
never even got compiled into the kernel or as a module.
* Drop the ds1, csa and maestro3 drivers due to restrictive license terms
or the need to use binary blobs. These drivers are not built by default
on FreeBSD.
