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. Signed-off-by: Tom Rini <trini@ti.com>
