ENGR00182054: [MX6]: always_present flag will't work as designed at some cond

As designed, when 'always_present' is set, it is assumed that cd_gpio should
be not set, and gpio_get_value(boarddata->cd_gpio) should return 0. But it is
not sure that the return value of gpio_get_value(0) is 0.

- check always_present first
- remove ESDHC_FLAG_GPIO_FOR_CD_WP flag if always_present is set.
