Subject: [PATCH v3] ARM: bcm: Add DEBUG_LL console support

This patch adds low level debug uart support to Broadcom
mobile based SOCs.

Signed-off-by: Christian Daudt <[email protected]>

Changes from V2:
- Changed to follow hex ordering on entries
- Dropped defconfig changes

Changes from V1:
- Switched to use the common 8250 debug introduced in 3.12-rc1
