[PATCH v2 01/35] mmc: sdhci: Use devm_mmc_alloc_host() helper

[Binbin Zhou]

Use new function devm_mmc_alloc_host() to simplify the code.

Although sdhci_free_host() is no longer needed, to avoid drivers that still
use this function from failing to compile, sdhci_free_host() is temporarily
set to empty. Finally, it will be removed when there are no more callers.
