Subject: clk: ti: clk-7xx: Remove hardwired ABE clock configuration
From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>
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")
