openwrt: Remove extra soc check in ath79_gpio_output_select (#965) 

The  assignment of the gpio_count and reg_base in ath79_gpio_output_select
takes care that only supported platforms can use ath79_gpio_output_select.
But the rebase of the patches after the last OpenWrt base update
accidentally added an extra check for the SoC which was missing support
soc_is_qca955x().

Boots on QCA955X devices which were using ath79_gpio_output_select stopped
with

    Kernel bug detected[#1]:
