Any reason to not use the devm_gpiod_get_index() managed version instead?

AFAICT mmc_free_host() will free the device so in that case you won't
need to call gpiod_put() in mmc_pwrseq_simple_free().

This will also make easier to extend pwrseq_simple to support multiple
GPIOs like the DT binding implies.

Best regards,
Javier
