The watchdog reset as done in brcmf_pcie_buscoreprep() is not
sufficient. It needs to modify PCIe core registers as well
which is properly done by brcmf_pcie_reset_device() after the
chip recognition is done. So the faulty watchdog reset can be
removed as it was causing driver reload to fail and hang the
system requiring a power-cycle. Instead the call to to the
brcmf_pcie_reset_device() function is done twice in the unload.

On device to host data using msgbuf the read pointer gets updated
once all data is processed. Updating this pointer more frequently
allows the firmware to add more data quicker. This will result in
slightly higher and more stable throughput on CPU bounded host
processors.

It seems Broadcom released two devices with conflicting device id. There
are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they
can be found in routers, e.g. Netgear WNR834Bv2. However, according to
Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY).
It's unsure if they meant PCI device id, or "virtual" id (from SPROM).
To distinguish these devices lets check PHY type (G vs. N).

Recently Broadcom added support for NVRAMs with entries for multiple
PCIe devices. One of the supported formats is based on prefixes defined
like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.

Unfortunately there are also a bit older devices using different way of
defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
devpath0=pci/1/1/
devpath1=pci/2/1
Broadcom stated this old format will never be used/supported by brcmfmac
but given the simplicity of this patch I'll insist on supporting it.
