ARM: dts: omap: am335x-mba335x: Fix stray '/*' in comment

When preprocessing arch/arm/boot/dts/ti/omap/am335x-mba335x.dts with
clang, there are a couple of warnings about '/*' within a block comment.

  arch/arm/boot/dts/ti/omap/am335x-mba335x.dts:260:7: warning: '/*' within block comment [-Wcomment]
    260 |                         /* /* gpmc_csn3.gpio2_0 - interrupt */
        |                            ^
  arch/arm/boot/dts/ti/omap/am335x-mba335x.dts:267:7: warning: '/*' within block comment [-Wcomment]
    267 |                         /* /* gpmc_ben1.gpio1_28 - interrupt */
        |                            ^

Remove the duplicate '/*' to clear up the warning.
