MIPS: TXx9: tx39xx: Move GPIO setup from .mem_setup() to .arch_init()
txx9_gpio_init() calls gpiochip_add_data(), which fails with -ENOMEM as
it is called too early in the boot process. This causes all subsequent
GPIO operations to fail silently.
Postpone all GPIO setup to .arch_init() time to fix this.
