Subject: [PATCH RESEND2 v2] clk: qcom: gcc-msm8939: Fix mclk0 & mclk1 for
 24 MHz

From: Vincent Knecht <vincent.knecht@...loo.org>

Fix mclk0 & mclk1 parent map to use correct GPLL6 configuration and
freq_tbl to use GPLL6 instead of GPLL0 so that they tick at 24 MHz.

Fixes: 1664014e4679 ("clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller")
