brcmfmac: coarse support for PCIe shared structure rev7
Revision 7 of PCIe dongle interface increases the item size of tx and rx
complete rings to accommodate extra payload for new feature. This patch
simply bump up the size of these two rings without adding the support
for utilizing the new space. This makes brcmfmac compatible with rev7
firmware.
