ARM: dts: microchip: sam9x7: fix gpio-lines count for pioB

[ Upstream commit 907150bbe566e23714a25d7bcb910f236c3c44c0 ]

The pioB controller on the SAM9X7 SoC actually supports 27 GPIO lines.
The previous value of 26 was incorrect, leading to the last pin being
unavailable for use by the GPIO subsystem.
Update the #gpio-lines property to reflect
the correct hardware specification.
