Subject: [PATCH 4.2 244/258] clk: ti: clk-7xx: Remove hardwired ABE clock configuration

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Ujfalusi <peter.ujfalusi@...com>

commit 4b3061b39132cba0c31b0eb767a9faeedf9437fc upstream.

The ABE related clocks should be configured via DT and not have it wired
inside of the kernel.

Fixes: a74c52def9ab ("clk: ti: clk-7xx: Correct ABE DPLL configuration")
