This adds a pinmux to the shared DTSI for TP-Link TL-WR841N/ND v8,
TL-WR842N v2 and TL-MR3420 v2. It is supposed to be the equivalent
of:
/* config gpio4 as normal gpio function */
ath79_gpio_output_select(TL_MR3420V2_GPIO_USB_POWER,AR934X_GPIO_OUT_GPIO);
This allows to enable USB power on these devices.
While at it, move the jtag_disable_pins to &gpio node and remove the
redundant status=okay there.
Tested on TP-Link TL-WR842N v2.
