mmc: pwrseq_simple: Fix incorrect handling of GPIO bitmap
Commit b9762bebc633 ("gpiolib: Pass bitmaps, not integer arrays, to
get/set array") changed the way GPIO values are passed to
gpiod_get/set_array_value() and friends. The new code introduced into
mmc_pwrseq_simple_set_gpios_value() incorrectly interpretes the 'value'
argument as a bitmap of GPIO values and assigns it directly to the
'values' bitmap variable passed to gpiod_set_array_value_cansleep()
instead of filling that bitmap with bits equal to the 'value' argument.
As a result, only member 0 of the array is handled correctly.
Moreover, wrong assumption is taken about the 'values' bitmap size not
exceding the number of bits of the 'value' argument type.
Fix it.
