[PATCH] mci: bcm2835: Set mci host for sdhci

[Jonas Richardsen <jonasrichardsen@emlix.com>]

The pointer `sdhci.mci` is currently not being set for the bcm2835. This
leads to a null pointer dereference for example in `sdhci_wait_idle()`
if the `sdhci_read` function fails or times out.

Set the pointer within the `bcm2835_mci_probe` function. This is
analogous to the behaviour seen in `arasan_sdhci_probe`,
`fsl_esdhc_probe`, `rk_sdhci_probe` and other, similar functions.
