davinci: make /proc/davinci_clocks display multi-rooted clock tree
This patch modifies clock dump to take care of clock tress rooted at multiple oscillators. Current code assumes the entire tree is rooted on a single oscillator. When using off-chip clock synthesizers, some of the clocks can be obtained from a different on-board oscillator.
