clk: tegra: export clock names for debugging
When writing a module for testing or debugging purposes, there is no way to get hold of clk handles. This patch solves this by exposing all valid clocks as clkdev's for the virtual device tegra-clk-debug. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
