[U-Boot] [PATCH] arm: am335x: add Kconfig range attribute to prevent invalid CONS_INDEX

[Masahiro Yamada]

The help message in board/ti/am335x/Kconfig says AM335x has
6 UARTs, so the valid number for CONFIG_CONS_INDEX is from 1 to 6.

BTW, why does CONFIG_CONS_INDEX start from 1, not 0.

CONFIG_CONS_INDEX=1 correponds to UART0 ?
