Mon Jan 14 12:41:03 UTC 2019
This adds common arch owl support that can drive, 64-bits SoCs
from Actions Semi.
It also removes the Bubblegum specific board files.
Signed-off-by: Amit Singh Tomar <amittomer25 at gmail.com>

Changes since v1:
* Moved S700 specific changes to patch 4 of 9.
* Moved couple of symbols from defconfig to arch/arm/Kconfig
and platform owl Kconfig.
