ath10k: fix AP/IBSS CSA with template based fw
qca6174 with wmi-tlv firmware uses offloaded
beaconing scheme (i.e. templates). This requires a
little different approach when implementing CSA.
Add missing code to update CS count and report CSA
completion to mac80211. Without it channel switch
was never finished.
To avoid races during interface teardown data_lock
has been used to protect is_up and is_started so
they can be compared against before scheduling
count down work.

cfg80211: Schedule timeout for all CRDA calls
Timeout was scheduled only in case CRDA was called due to user hints,
but was not scheduled for other cases. This can result in regulatory
hint processing getting stuck in case that there is no CRDA configured.
Change this by scheduling a timeout every time CRDA is called. In
addition, in restore_regulatory_settings() all pending requests are
restored (and not only the user ones).

cfg80211: Add API to change the indoor regulatory setting
Previously, the indoor setting configuration assumed that as
long as a station interface is connected, the indoor environment
setting does not change. However, this assumption is problematic
as:
- It is possible that a station interface is connected to a mobile
AP, e.g., softAP or a P2P GO, where it is possible that both the
station and the mobile AP move out of the indoor environment making
the indoor setting invalid. In such a case, user space has no way to
invalidate the setting.
- A station interface disconnection does not necessarily imply that
the device is no longer operating in an indoor environment, e.g.,
it is possible that the station interface is roaming but is still
stays indoor.
To handle the above, extend the indoor configuration API to allow
user space to indicate a change of indoor settings, and allow it to
indicate weather it controls the indoor setting, such that:
1. If the user space process explicitly indicates that it is going
to control the indoor setting, do not clear the indoor setting
internally, unless the socket is released. The user space process
should use the NL80211_ATTR_SOCKET_OWNER attribute in the command
to state that it is going to control the indoor setting.
2. Reset the indoor setting when restoring the regulatory settings in
case it is not owned by a user space process.
Based on the above, a user space tool that continuously monitors the
indoor settings, i.e., tracking power setting, location etc., can
indicate environment changes to the regulatory core.
It should be noted that currently user space is the only provided mechanism
used to hint to the regulatory core over the indoor/outdoor environment --
while the country IEs do have an environment setting this has been completely
ignored by the regulatory core by design for a while now since country IEs
typically can contain bogus data.

bcma: prepare Kconfig symbol for PCI driver
Driver for PCIe core requires PCI to be enabled, however we shouldn't
require it for the whole bus. Someone may be not interested in extra
PCI devices and what's more there are SoCs without any PCI at all (like
BCM5356C0, BCM5357*, BCM47186B0). For more details see Kconfig "help".
Please note this patch doesn't allow disabling PCI drivers yet, as it
requires more work on calls to bcma_core_pci_* functions.
