board_r: run scsi init() on ARM too

This has been disabled for ARM in initr_scsi since that function was introduced. However it works fine for me on Cubieboard and Cubietruck (with the upcoming AHCI glue patch).

I also tested on two random ARM platforms which seem to define CONFIG_CMD_SCSI:
- highbank worked fine (on midway hardware)
- omap5_uevm built OK and I confirmed using objdump that things were as expected (i.e. the default weak scsi_init nop was used).

While there remove the mismatched comment from the #endif (omitting the comment seems to be the prevailing style in this file).
