ARM: uniphier: insert udelay() just before support_card_reset_deassert()
As for LD11/LD20, we can no longer rely on the udelay() in the PLL
init functions. udelay(200) is needed here to keep the ethernet
device in the reset state for enough time. Anyway, 200 usec is
quite short for humans, so nobody cares it.
