[PATCH] clk: qcom: ipq8074: Use floor ops for SDCC1 clock

[Robert Marko <robimarko@gmail.com>]

From: Dirk Buchwalder <buchwalder@posteo.de>

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")
