[RFC PATCH] ARM: cache-l2x0: add setup entry for l2 in non-secure mode

[Gioh Kim]

Hi,

My board is using Trustzone and running kernel is non-secure mode.
But setup function of PL310 driver is only for secure mode kernel.

What about adding an entry for non-secure mode setup function?

I'm sorry for my poor code but I just wanna say what I need .
