Remove lint_off in ram.v

[adumont]

Had to place some ugly lint_off inline comments in ram.v. Need to find a way to code it better so verilator lint won't complain about it:

        /* verilator lint_off WIDTH */
        if( ROMFILE ) $readmemh(ROMFILE, mem);
        /* verilator lint_on WIDTH */

Verilator says: %Warning-WIDTH: ram.v:23: Logical Operator IF expects 1 bit on the If, but If's VARREF 'ROMFILE' generates 104 bits.

See https://github.com/ZipCPU/icozip/blob/master/rtl/icozip/memdev.v#L70 for another way to preload RAM/ROM, using a generate block:

    generate if (HEXFILE != 0)
    begin : PRELOAD_MEMORY
        initial $readmemh(HEXFILE, mem);
    end endgenerate
