mmc: mv_sdhci: fix uninitialized pointer deref on probe

Since commit 3d296365e4e8 ("mmc: sdhci: Add support for
sdhci-caps-mask") sdhci_setup_cfg() expects a valid sdhci_host mmc
field. Move the mmc field initialization before sdhci_setup_cfg()
call to avoid crash on mmc pointer dereference.

Fixes: 3d296365e4e8 ("mmc: sdhci: Add support for sdhci-caps-mask")
