Subject: [PATCH 1/7] brcmfmac: reset two D11 cores if chip has two D11 cores
There are two D11 cores in RSDB chips like 4359. We have to reset two
D11 cores simutaneously before firmware download, or the firmware may
not be initialized correctly and cause "fw initialized failed" error.

Subject: [PATCH 7/7] brcmfmac: not set mbss in vif if firmware does not
support MBSS
With RSDB mode, FMAC and firmware are able to create 2 or more AP,
so we should not set mbss in vif structure if firmware does not
support MBSS feature.
