[PATCH 2/2] pinctrl: meson-axg: correct the pin expansion of UART_AO_B

[Yixun Lan]

The 'uart_ao_b_groups' for the UART_AO_B pins is already defined which is
living inside the AO domain, for these pins which are routed out from EE domain,
we need to correct them with the 'FUNCTION_EX' macro, otherwise there is
a conflict in the code level.

Also slightly adjust the name to make it short and more consistent.
