[U-Boot] [PATCH v2 3/8] ARM: keystone2: Cleanup PLL init code

Tue Jul 28 10:46:43 CEST 2015
There are two types of PLL for all keystone platforms:
Main PLL, Secondary PLL. Instead of duplicating the same definition
for each secondary PLL, have a common function which does
initialization for both PLLs. And also add proper register
definitions.
