media: sta2x11: Use gpio_is_valid() and remove unnecessary check

Browse source

Replace the manual validity checks for the GPIO with the
gpio_is_valid().

In vip_gpio_reserve(), Error checking for gpio pin is not correct.
If pwr_pin = -1, It will return 0. This should be return an error.

In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin'
is unnecessary. Because vip_gpio_reserve() is also checking for
valid gpio pin. So removed extra error checking for gpio 'reset_pin'.
