mmc: mtk-sd: increase the minimum bus frequency
With a 48MHz input clock, the lowest bus frequency can be as low as
48000000 / (4 * 4095) = 2930Hz. Such an extremely low frequency will cause
the mmc framework take seconds to finish the initialization.
Limiting the minimum bus frequency to a slightly higher value can solve the
issue without any side effects.
