MIPS: TXx9: tx49xx: 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 (before commit 54d77198fdfbc4f0 ("gpio:
bail out silently on NULL descriptors") it printed the error message
"gpiod_direction_output_raw: invalid GPIO" on RBTX49[23]7).
Postpone all GPIO setup to .arch_init() time to fix this.
