[PATCH] mmc: mmc_spi: Use proper debounce time for CD GPIO

[Thierry Reding]

From: Thierry Reding <treding@xxxxxxxxxx>

According to the comment, board files used to specify 1 ms for the
debounce time. gpiod_set_debounce() needs the debounce time to be
specified in units of microseconds, so make sure to multiply the value
by 1000.

Note that, according to the git log, the board files actually did
specify 1 us for bounce times, but that seems really low. Device tree
bindings for this type of GPIO typically specify the debounce times in
milliseconds, so setting this default value to 1 ms seems like it would
be somewhat safer.
