It's useful to know an error number when it's debugging.

At least this one needs to be printf() not puts(). This causes build
failures for any board that compiles this code, i.e. anything with the
following enabled:

static int mmc_power_on(struct mmc *mmc)
{
#if CONFIG_IS_ENABLED(DM_MMC) && CONFIG_IS_ENABLED(DM_REGULATOR)
