mmc: at91_mci: reorder timer setup and mmc_add_host() call
As said in function comment mmc_add_host() requires that:
"The host must be prepared to start servicing requests
before this function completes."
During this function, at91_mci_request() can be invoqued
without timer beeing setup leading to a kernel Oops.
This has been reported inserting this driver as a module.
