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.
