[PATCH 4.4-cip] spi: pxa2xx: Fix build error because of missing header

Ben Hutchings <ben.hutchings@...>

From: Mika Westerberg <mika.westerberg@...>

commit 089bd46d8bc1fe5a28351e82e4adcaa5a40121b5 upstream.

Kbuild test robot reports:

drivers/spi/spi-pxa2xx.c: In function ‘setup_cs’:
drivers/spi/spi-pxa2xx.c:1190:20: error: implicit declaration of function ‘desc_to_gpio’

Reason for this is the fact that those functions are declared in
linux/gpio/consumer.h which is not included in the driver. Fix this by
including it.

This fixes a build regression for some configurations since I applied
the backport of commit 3d3bc50700ba "spi: pxa2xx: Add support for GPIO
descriptor chip selects".
