am335x_evm: Convert CONFIG_CONS_INDEX into a menu choice
- Drop CONFIG_SERIAL[1-6] and use CONFIG_CONS_INDEX tests instead
- Add choice and help text to board/ti/am335x/Kconfig
- Correct comment about IDK in board/ti/am335x/mux.c
- Remove am335x_evm_uart* defconfig files as they're just variations
on a config option now.

+ The AM335x SoC has a total of 6 UARTs (UART0 to UART5 as referenced
+ in documentation, etc) available to it. Depending on your specific
+ board you may want something other than UART0 as for example the IDK
+ uses UART3 so enter 4 here.
