[U-Boot] [PATCH v4 4/4] am335x_evm: Enable use of UART{1,2,3,4,5}

Add targets of am335x_evm_uart{1,2,3,4,5} to have serial input/output on
UART{1,2,3,4,5} for use with the Beaglebone RS232 cape, am335x_evm
daughterboard, and other custom configurations.
Modify target for am335x_evm to include SERIAL1 and CONS_INDEX=1
options in order to clarify UART selection requirements.

Changes from v3:
All am335x_evm targets get SERIALX without a 1 and CONS_INDEX=X
defined in boards.cfg. am335x_evm.h no longer define any
CONFIG_SERIALX or CONFIG_CONS_INDEX.
Changes from v2:
Set CONS_INDEX and SERIALX in the target options instead of
using AM33XX_UART_SELECT resulting in an easier to read config.
Changes from v1:
Add UART3 target and register location.
