This commit removes the programming sequence that enables PLLE and UPHY PLL hardware power sequencers. Per TRM, boot software should enable PLLE and UPHY PLLs in software controlled power-on state and should power down PLL before jumping into kernel or the next stage boot software. Adds call to board_cleanup_before_linux to facilitate this. Signed-off-by: JC Kuo <jckuo@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com>
