device so we use syscon (and regmap) for it.

V2: Rebase on top of clk-next
Use ALP as parent clock
Improve comments
Switch from ioremap_nocache to ioremap
Check of_clk_add_provide result for error
V3: Drop #include <linux/moduleh>
Make ILP DT entry part of PMU
Describe ILP as subdevice of PMU in Documentation
V4: Use BCM53573 name as suggested by Jon and Ray. It seems "Northstar"
(even if used in some resources) should be used in relation to
Cortex-A9 devices only.
V5: Rename remaining "ns" references to "bcm53573", sorry, I sent V4 too
early.
V6: Drop #include <linux/clk.h>
Use "int" as type where it matches usage
Add cpu_relax() in the loop
Add disable callback
Use _hw_ functions for registering struct clk_hw (new API)
Thanks a lot Stephen!
V7: Use syscon and regmap (thanks Rob!)
V8: Update Documentation (drop unused "reg", unit address)
