[U-Boot] [Patch V3] ARM: da850evm_direct_nor_defconfig: Enable DM_SERIAL

[Adam Ford]

With DM enabled, this patch enables DM_SERIAL and removes
the NS16550 initialization from da850_lowlevel since the driver
will take care of that itself.

V3:  Make the include items referencing the serial info 
     dependent on DM_SERIAL and not SPL or NOR since
     both of these options will eventually use DM_SERIAL.

V2:  Rebase against Master
     Use CONFIG_IS_ENABLED instead of defined so this can be 
     enabled/disabled in SPL independently.
     Enable CONFIG_SYS_MALLOC_F to allow relocation allowing the serial to build correctly
