Subject: [PATCH 1/3] clk: qcom: gcc-msm8976: Set floor ops for SDCC

Just like in case of other SoCs change SDCC1/SDCC2 ops to floor to avoid overclocking controller.
This commit only sets SDCC1/SDCC2 which are used for EMMC/SDCARD.
It leaves SDCC3 because on this platform it's mostly used for WIFI/BT chips like on Sony Loire family devices.
