[PATCH v3] media: rc: add keymap for pine64 remote

[Christian Hewitt]

From: Jonas Karlman <jonas@kwiboo.se>

Add a keymap for the pine64 IR remote [0]. The mouse key has been mapped to
KEY_EPG to provide a more useful remote.

Changes since v2:
- added missing rc-map.h change

Changes since v1 [1]:
- reorder code to match the physical layout
- assign KEY_EPG instead of KEY_CONTEXT_MENU

KEY_CONTEXT_MENU duplicates KEY_MENU, and while Seans suggestion of BTN_LEFT
visually matches the key, this duplicates KEY_OK in most GUI's designed for
remote naviagation, e.g. Kodi and Plex. I've chosen to map KEY_EPG as this
is a common tweak in user forums to extend IR remote functionality.
