radio-iris: Return hardware capabilities

- Radio iris isn't properly advertising its hardware capabilities to
  userspace which makes it look like radio is unsupported.
  Fix this so that userspace sees that radio is in fact supported
- Upadate the hardware capabilities while returning response to query
  device capabilities.

qseecom: Ensure incoming "app_name" does not corrupt the kernel stack

Printing a string with that does not have null terminated character,
would lead to overflow, as the print continues until it finds a null
terminated character.
Avoid this issue by explicitly assigning a string with null termination.

cfg80211: add flags to define country IE processing rules

802.11 cards may have different country IE parsing behavioural
preferences and vendors may want to support these. These preferences
were managed by the WIPHY_FLAG_CUSTOM_REGULATORY and the
WIPHY_FLAG_STRICT_REGULATORY flags and their combination.
Instead of using this existing notation, split out the country IE
behavioural preferences to a new flag. This will allow us to add more
customizations easily and make the code more maintainable. Also add
a new flag to disable country IE hints issued by the CORE as the
first customization.

crypto: msm: Fix issues related to non-zero byteoffset input

Fix buffer overflow for a non-zero byteoffset value.

Also fixes memory leak issue by adding data_len check in check_params.
One of the scenarios data_len can be less than byteoffset which results
in memory leak with huge data length, which might cause the kernel panic.
