[PATCH v2 1/2] gpio: aggregator: Drop pre-initialization in get_arg()

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

In get_arg(), the variable start is pre-initialized, but overwritten
again in the first statement.  Rework the assignment to not rely on
pre-initialization, to make the code easier to read.
