[PATCH 09/11] soc: ti: knav_dma: Remove dead check on unsigned args.args[0]

[Nishanth Menon <nm@ti.com>]

smatch warns:

  knav_dma.c:390 of_channel_match_helper() warn: unsigned
  'args.args[0]' is never less than zero.

of_phandle_args.args[] is uint32_t, so the 'args.args[0] < 0' check
is always false. of_parse_phandle_with_fixed_args() already handles
errors by returning a non-zero code, which is checked immediately
above. Remove the dead check.
