Move aliases to board dts and trim the list to interfaces that are
enabled.
Alias main_uart8 to serial2 so as to use ttyS2 as console on all K3 SoCs

Aliases are board specific and should be in board dts files.
So, move aliases to board dts and trim the list to interfaces that are
actually enabled.

From: Aswath Govindraju <a-govindraju@ti.com>

On J721s2 Linux console is on main_uart8 but to be consistent with other
J7 family of devices, alias it to ttyS2 (serial2). This also eliminates
need to have higher number of 8250 runtime UARTs.
