[U-Boot] AVIC initialization in Uboot for mx31 pdk

[alfred steele]

Hi Magnus/all,

I believe that  AVIC has to be initialized for the MX31 PDK for
getting any peripheral based interrupt to work.  I did not find any
instance of it in the latest MX31 PDK patch, or am i missing anything.
 If we are assuming that this responsibility gets transferred to the
kernel, then its fine.
Please correct me if i am wrong. If it has to be done in U-boot, what
would be an approriate place to do it.

Please correct me if i am wrong.
-Alfred.
