This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers. This batch converts
the drivers that appeared to have been added after kernel 5.4.

Remove the 'of_match_ptr()' macro to fix the warning when CONFIG_OF is
not selected.

For commands that doesn't involve to prepare a data transfer, owl-mmc is
using a fixed 30s response timeout. This is a bit problematic.
For some commands it means waiting longer than needed for the completion to
expire, which may not a big issue, but still. For other commands, like for
an erase (CMD38) that uses a R1B response, may require longer timeouts than
30s. In these cases, we may end up treating the command as it failed, while
it just needed some more time to complete successfully.
Fix the problem by respecting the cmd->busy_timeout, which is provided by
the mmc core.

dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.
By using dma_request_chan() directly the driver can support deferred
probing against DMA.

Add SD/MMC driver for Actions Semi Owl SoCs. This driver currently
supports standard, high speed, SDR12, SDR25 and SDR50. DDR50 mode is
supported but it is untested. There is no SDIO support for now.
