mci: bcm2835: reset host controller on barebox shutdown
We don't usually disable MMC controllers on barebox shutdown, because they don't DMA on their own, unlike e.g. network controllers. Booting Linux v5.17.0 on a Raspberry Pi 4 in 32-bit mode still has the MMC host controller driver complain: [ 22.464887] mmc1: Got data interrupt 0x00000002 even though no data operation was in progress. Fix this by resetting the SDHCI once barebox is done with it.
