The firmware for brcmfmac devices includes information regarding
regulatory constraints. For certain devices this information is kept
separately in a binary form that needs to be downloaded to the device.
This patch adds support to download this so-called CLM blob file. It
uses the same naming scheme as the other firmware files with extension
of .clm_blob.
The CLM blob file is optional. If the file does not exist, the download
process will be bypassed. It will not affect the driver loading.

Since commit 9cc4b7cb86 ("brcmfmac: Make skb header writable
before use") the headroom usage has been fixed. However, the
driver was keeping statistics that got lost. So reworking the
code so we get those driver statistics back for debugging.

The statistic counter is used in common layer and in the bus layer
in different thread contexts so change to use atomic operations.

This intends to make init/attach process slightly easier to follow.
What driver was doing in brcmf_bus_start wasn't bus specific at all and
function brcmf_bus_stop wasn't undoing things done there. This function
is supposed to be called by bus specific code when the bus is ready.

Functions brcmf_c_prec_enq and brcmf_sdio_init don't exist so we
really don't need their declarations. Function brcmf_parse_tlvs is used
in cfg80211.c only so make it static and drop from header as well.

Move event handling out of brcmf_netif_rx() avoiding the need
to pass a flag. This flag is only ever true for USB hosts as
other interface use separate brcmf_rx_event() function.

Firmware uses asynchronized events as a communication method to the
host. The event packets are marked as ETH_P_LINK_CTL protocol type. For
SDIO and PCIe bus, this kind of packets are delivered through virtual
event channel not data channel. This patch adds a screening logic to
make sure the event handler only processes the events coming from the
correct channel.

Merge module parameters and platform data in one struct. This is the
last step to move to the new platform data per device. Now parameters
of platform data will be merged with module parameters per device.
