mac80211: backport some brcmfmac patches

Browse source 
There are two important patches in this patchset: updating read pointer
quicker & rework of .get_station().
There are few more upstream patches that are p2p-related and weren't
backported in this commit.

Subject: [PATCH] brcmfmac: Update msgbuf read pointer quicker.
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.

Subject: [PATCH] brcmfmac: remove watchdog reset from
brcmf_pcie_buscoreprep()
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.

Subject: [PATCH] brcmfmac: use debugfs_create_devm_seqfile() helper
function
Some time ago the function debugfs_create_devm_seqfile() was
introduced in debugfs. The caller simply needs to provide a
device pointer and read function. The function brcmf_debugfs_add_entry()
is now simply a wrapper only doing the work for CONFIG_BRCMDBG.

Subject: [PATCH] brcmfmac: have sdio return -EIO when device communication
is not possible
The bus interface functions txctl and rxctl may be used while the device
can not be accessed, eg. upon driver .remove() callback. This patch will
immediately return -EIO when this is the case which speeds up the module
unload.
