Initialize tree pointers in the dump only option

The regulator, gpio, sensor and clock tree pointers were
initialized only during the display option and not during the
dump only option. This meant the dump option was not printing
any info previously. This patch fixes it by initilaizing the
tree pointers during the dump only option.
