[PATCH] mmc: iproc_sdhci: Cannot test unsigned variable for negative

[Andrew Goodbody]

In sdhci_iproc_execute_tuning the variable tuning_loop_counter is
unsigned and therefore will always fail the test for it being less than
0. Fix this by changing the variable type to be s8.

This issue was found by Smatch.
