Ulf Hansson 1433269c4d mmc: core: Export a function mmc_sw_reset() to allow soft reset of cards ... It's rather common that a firmware is loaded into an SDIO func device memory, by the corresponding SDIO func driver during ->probe() time. However, to actually start running the new firmware, sometimes a soft reset (no power cycle) and a re-initialization of the card is needed. This is for example the case with the Espressif ESP8089 WiFi chips, when connected to an SDIO interface. To cope with this scenario, let's add a new exported function, mmc_sw_reset(), which may be called when a soft reset and re-initialization of the card are needed. The mmc_sw_reset() is implemented on top of a new bus ops callback, similar to how the mmc_hw_reset() has been implemented.
