[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
