Subject: clk: qoriq: add pll clock to clock lookup table
Git-commit: 45899dc5f1b5107903b2bc1c78e22d7945a895fd
Patch-mainline: v4.14-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
Register each PLL and its division clocks to clock
lookup table to facilitate the clock look up for
clock consumer.
