leds: leds-st1202: Spacing and proofreading editing

Minor edits regarding use of spacing and proofreading.

There is a minor inconsistency in the use of spacing as margin in
one of the comments providing details about the datasheet.

There is also a typo that comes from the datasheet itself.

Change spacing on comment and correct typo.
