MIPS: TXx9: Disable PM capability of TX493[89] internal ether
Some TC35815 variants (i.e. TX493[89] internal ether) report existance of PM registers though they are not supported. Disable PM features by clearing pdev->pm_cap. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
