Use voltage range as below rather than a specific value
3.3v: (3.2v, 3.4v)
3.0v: (2.9v, 3.1v)
1.8v: (1.65v, 1.95v)

Commands without data transfer like cmd5/cmd7 will use previous
transfer mode setting, which may lead to error since some bits
may have been set unexpectedly.
For example, cmd5 following cmd18/cmd25 will have timeout error
since audo cmd23 has been enabled.

A power gpio is a sideband output gpio that controls card power.

Changelog:
v2, addressing Guennadi's review comments:
- More consistent comment and operator coding style
- Only store pwr_gpio in ctx if requesting it was successful
- Use GPIOF_OUT_INIT_{LOW,HIGH}
mmc_gpio_request_ro() doesn't store the requested gpio in ctx->ro_gpio.
As a result, subsequent calls to mmc_gpio_get_ro() will always fail
with -ENOSYS because the gpio number isn't available to that function.

Hi Guennadi,
Thanks for getting to this review so quickly! I agree with all of your
comments. I'm sending out v2 of both patches now.

Looks good in general to me, thanks! Just a couple of nit-picks below.

I didn't quite understand everything that you meant in your mail, however I
will try to explain briefly:
SANITIZE replaces the need to issue REQ_SECURE as part of the REQ_DISCARD
request. In this way DISCARD request finishes much faster (order of
magnitude) and thus improves system performance. Wh
