> Use floor ops on SDCC1 APPS clock in order to round down selected clock
> frequency and avoid overclocking SD/eMMC cards.
>
> For example, currently HS200 cards were failling tuning as they were
> actually being clocked at 384MHz instead of 192MHz.
> This caused some boards to disable 1.8V I/O and force the eMMC into the
> standard HS mode (50MHz) and that appeared to work despite the eMMC being
> overclocked to 96Mhz in that case.
>
> There was a previous commit to use floor ops on SDCC clocks, but it looks
> to have only covered SDCC2 clock.
>
> Fixes: 9607f6224b39 ("clk: qcom: ipq8074: add PCIE, USB and SDCC clocks")
