ARM: OMAP: omap3evm: cleanup revision bits
The omap3evm has its revision information bits inside the plat/board.h file. Those bits are not used anywhere in the upstream tree besides the board-omap3evm.c file. Move the OMAP3EVM_BOARD_GEN_* bits to the board file and remove the get_omap3_evm_rev() function declaration.
