Eero Nurkkala e5305a250a risc-v/mpfs: emmcsd: provide options for selecting clk speed
Some related products, such as Aries m100pfs, don't support eMMC
speeds up to 200MHz. Thus, provide option to select slower clock.
This has only to do with the clocking, no CMD6 is sent to select
high speed modes.
