[PATCH] clk: Add requested rate to clock summary output

[Peter De Schrijver]

From: Alex Frid <afrid@xxxxxxxxxx>

Added requested rate to clock summary output and to clock dump. This is
useful for clock tree debugging. Also expand the clock name field in the
clock tree debugfs output to provide room for deep multi-tier trees like
on Tegra.
