This provides SPL support for T114 boards - AVP early init, plus CPU (A15) init/jump to main U-Boot.

Signed-off-by: Tom Warren twarren@nvidia.com --- Changes in v2: - update all new copyright header dates to 2013 - use CHIPID directly to figure num cpus - set CPU2/3 bits at runtime using num cpus instead of ifdef - remove private TRUE/FALSE defines, not needed now - clrbits/setbits_le32 used instead of reg read/&/|/write Changes in v3: - only need to powerup the fast cluster
