Revert "mmc: sdhci: set to INT_DATA_END when there are data"

This reverts commit 17ea3c862865c0d704646f67dbf8412f9ff54f59.

In eMMC specification, for the response-with-busy(R1b, R5b)
command, the DAT0 will driven to LOW as BUSY status, and in
sdhci specification, the transfer complete bit should be wait
for BUSY status de-assert.

All response-with-busy commands don't contain data, the data
judgement is no need.
