[PATCH] mmc: exynos_dw_mmc: guard execute_tuning

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Guard execute_tuning with MMC_SUPPORTS_TUNING, otherwise there will be
build failure:
drivers/mmc/exynos_dw_mmc.c:484:10: error: 'struct dm_mmc_ops' has no member
named 'execute_tuning'
         .execute_tuning = exynos_dwmmc_execute_tuning,
          ^~~~~~~~~~~~~~
