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

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")

v2 :
  - Added tags from Konrad and Bryan
  - Mainly a resend because v1 didn't make it into lore and patchwork
