there are too many error logs shown when use CMD21/CMD19 to do tune,
and it will appear at each resume time, print out so many logs to the
uart console cost too mush time. so change it to dev_dbg.

drivers/mmc/host/mtk-sd.c: In function ‘get_best_delay’:
drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.start’ is used uninitialized in this function
drivers/mmc/host/mtk-sd.c:1284: warning: ‘delay_phase.maxlen’ is used uninitialized in this function
If delay is zero, these fields are indeed not initialized.
Let the compiler preinitialize the whole struct to fix this.

Even if we only use one gpd, we need alloc 2 gpd and make
the gpd->next pointer to the second gpd, or may get gpd checksum
error, this was checked by hardware

use the ios->timing directly is better
It can reflect current timing and do settings by timing
