arm: kirkwood: pogo_v4: Add Distro boot capability

Browse Source 
- Add distro boot to board include file and deconfig file
- Miscellaneous changes:
	- Add CONFIG_SUPPORT_PASSING_ATAGS and friends to support legacy
	kernel method of booting (e.g. OpenWrt) with appended DTB.
	- Add CONFIG_LTO and CONFIG_UBIFS_SILENCE_MSG, and disable some
	unused configs	to reduce binary size.

Note that this patch is depended on the following patch:
