[PATCH 2/4] mci: dwcmshc-sdhci: Fix f_max computation

[Yann Sionneau]

f_max was possibly set from max-frequency DT property
by mci_of_parse() and then overwritten few lines later
with the clock frequency, making it impossible to
reduce the clock frequency from DT.

Move the call to mci_of_parse() after the first assignment
to f_max.
