configs: mx23_olinuxino_defconfig: fix status led definition

While migrating individual status led usages to Kconfig stuff,
a (random) value was introduced for this board which does not
work but produces the following error message during boot:

__led_init: failed requesting GPIO59!

Since Kconfig does not seem to accept a define as this point,
but the mxs gpio driver requires not only a simple integer value,
we need to use the plain value of MX23_PAD_SSP1_DETECT__GPIO_2_1.
