mmc: sdhci-esdhc-imx: fix few build warnings

drivers/mmc/host/sdhci-esdhc-imx.c:1566 sdhci_esdhc_imx_hwinit() warn: inconsistent indenting
drivers/mmc/host/sdhci-esdhc-imx.c:1251 esdhc_executing_tuning() error: uninitialized symbol 'target_min'.
drivers/mmc/host/sdhci-esdhc-imx.c:1251 esdhc_executing_tuning() error: uninitialized symbol 'target_max'.

Fixes: be953af ("mmc: sdhci-esdhc-imx: widen auto-tuning window for standard tuning")
Fixes: 541a95e ("mmc: sdhci-esdhc-imx: optimize the manual tuing logic to get the best timing")
