* check 101

* Add 101 Armbian patches as series

Patches are renamed using the logic of the file structure
and the essence of the changes, sorted in the order
of their receipt. Fixed a lot of incorrect overlay
of some pieces in patches. Several small patches are
combined, because they changed one file.

Subject: [PATCH 302/476] Bluetooth: Add new quirk for broken local ext
features max_page
Some adapters (e.g. RTL8723CS) advertise that they have more than
2 pages for local ext features, but they don't support any features
declared in these pages. RTL8723CS reports max_page = 2 and declares
support for sync train and secure connection, but it responds with
either garbage or with error in status on corresponding commands.
