[PATCH] minor clean up and update to tlclk.c for 2.6.15-rc2-git2

[Mark Gross <mgross@linux.intel.com>]

This time without the HTLM :(  

The following cleans up the telecom clock driver for the MPCBL0010.  
There was a small TPS change that this update relflects.
There where some non-static functions that are now static.
