ASoC: simple-card: Initialize headphone and mic GPIO numbers

The uninitialized default of 0 for gpio_hp_det and gpio_mic_det doesn't
play well with asm-generic's gpio_is_valid():

static inline bool gpio_is_valid(int number)
{
return number >= 0 && number < ARCH_NR_GPIOS;
}

Hence on r8a7740/armadillo-legacy:

sh-mobile-hdmi sh-mobile-hdmi: SH Mobile HDMI Audio Codec
sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones
sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Mic Jack

After that the kernel log is spammed ca. 7 times per second with:

sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones

Initialize the GPIO numbers with a negative number (-ENOENT) to fix this.
