[PATCH] ARM: dts: at91: sama5d2_ptc_ek: fix nand pinctrl

[Ludovic Desroches]

The drive strength has to be set to medium otherwise some data
corruption may happen.

Hi,

This fix depends on the support of the drive-strength for the atmel pio4
pinctroller. It has been added in v4.19 but I omitted to send it at the
same time.
