am33xx: Remove board/ti/am335x/evm.c

The intention has always been (and boards are to support) an i2c EEPROM
that will identify what hardware they are, allowing a single binary to
support multiple boards.  As such, remove the 'evm.c' file as there is
nothing EVM centric in it currently, only SoC peripheral configuration.
