Add basic bwn(4) support for the (BCMA-based) BCM43224 and BCM43225.

• Add the BCM4322X D11 core revision and missing BCM43224 PCI device ID to our device tables.
• Disable the DMA engine parity check (rather than adding parity support to the to-be-replaced bwn(4) DMA implementation).

Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by
default. Until this is replaced with Broadcom's ISC-licensed N-PHY
implementation, bwn(4) must be rebuilt to enable N-PHY support.

To build bwn(4) with N-PHY support, add the following lines to your kernel
configuration file and rebuild the kernel (and modules):

options BWN_GPL_PHY

To test bwn(4) with a BCM43224/BCM43225 device, install the firmware from
the net/bwn-firmware-kmod port, and place the following lines in
loader.conf(5):

hw.bwn_pci.preferred="1"

if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"
bwn_v4_n_ucode_load="YES"
bwn_v4_lp_ucode_load="YES"
