Subject: [PATCH] clk: qcom: gcc-sdm660: Use floor ops for SDCC1 clock

In commit 3f905469c8ce ("clk: qcom: gcc: Use floor ops for SDCC clocks")
floor ops were applied to SDCC2 only, but flooring is also required on
the SDCC1 apps clock which is used by the eMMC card on Sony's Nile
platform, and otherwise result in the typicial "Card appears
overclocked" warnings observed on many other platforms before:

    mmc0: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
    mmc0: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
    mmc0: Card appears overclocked; req 104000000 Hz, actual 192000000 Hz
