[ARM] tegra: Add clock support

v2: fixes from Russell King: - include linux/io.h instead of asm/io.h - fix whitespace in Kconfig - Use spin_lock_init to initialize lock - Return -ENOSYS instead of BUG for unimplemented clock ops - Use proper return values in tegra2 clock ops additional changes: - Rename some clocks to match dev_ids - add rate propagation - add debugfs entries - add support for clock listed in clk_lookup under multiple dev_ids v3: - Replace per-clock locking with global clock lock - Autodetect clock state on init - Let clock dividers pick next lower possible frequency - Add support for clock init tables - Minor bug fixes - Fix checkpatch issues Signed-off-by: Colin Cross <ccross@android.com>
