mmc: sdhci: Constify sdhci_ops structs where possible 

Author: Lars-Peter Clausen <lars@metafoo.de>

Basically all drivers can have sdhci_ops struct const, but almost none do.
This patch constifies all sdhci_ops struct declarations where possible.

The patch was auto-generated with the following coccinelle semantic patch:

// 
@r1@
identifier ops;
identifier fld;
@@
ops.fld = ...;

@disable optional_qualifier@
identifier ops != r1.ops;
@@
static
+const
struct sdhci_ops ops = { ... };
//
