[PATCH v2025.09.y 04/58] mci: am654-sdhci: Wait for transfer complete interrupt with MMC_RSP_BUSY cmd

[Ahmad Fatoum]

From: Sascha Hauer <s.hauer at pengutronix.de>

The MMC_RSP_BUSY flag indicates that we have to wait for the transfer
completion interrupt. Other SDHCI drivers do this, but the am654 driver
missed it.

(cherry picked from commit 0b7c6416b9684a2c304cf18366c5feb3b4a38867)
