staging/olpc_dcon: fix kconfig to fix build errors
Fix build errors when GPIO_CS5535=m and FB_OLPC_DCON=y
by preventing that kconfig combination.
These build errors are caused by having a kconfig bool symbol
(FB_OLPC_DCON_1) that depend on a tristate symbol (GPIO_CS5535),
but when the tristate symbol is =m, the bool symbol is =y.
drivers/built-in.o: In function `dcon_read_status_xo_1':
olpc_dcon_xo_1.c:(.text+0x359531): undefined reference to `cs5535_gpio_set'
drivers/built-in.o: In function `dcon_wiggle_xo_1':
olpc_dcon_xo_1.c:(.text+0x35959f): undefined reference to `cs5535_gpio_set'
olpc_dcon_xo_1.c:(.text+0x359610): undefined reference to `cs5535_gpio_clear'

drivers/built-in.o: In function `dcon_init_xo_1':
olpc_dcon_xo_1.c:(.text+0x35989b): undefined reference to `cs5535_gpio_clear'
olpc_dcon_xo_1.c:(.text+0x3598b5): undefined reference to `cs5535_gpio_isset'
olpc_dcon_xo_1.c:(.text+0x359963): undefined reference to `cs5535_gpio_setup_event'
olpc_dcon_xo_1.c:(.text+0x359980): undefined reference to `cs5535_gpio_set_irq'
olpc_dcon_xo_1.c:(.text+0x359a36): undefined reference to `cs5535_gpio_set'
However, adding GPIO_CS5535 to the Kconfig dependencies also creates
a kconfig recursive dependency error on powerpc:
drivers/i2c/Kconfig:5:error: recursive dependency detected!
drivers/i2c/Kconfig:5: symbol I2C is selected by FB_OLPC_DCON
drivers/staging/olpc_dcon/Kconfig:1: symbol FB_OLPC_DCON depends on GPIO_CS5535
drivers/gpio/Kconfig:577: symbol GPIO_CS5535 depends on GPIOLIB
drivers/gpio/Kconfig:38: symbol GPIOLIB is selected by ARCH_REQUIRE_GPIOLIB
drivers/gpio/Kconfig:23: symbol ARCH_REQUIRE_GPIOLIB is selected by MCU_MPC8349EMITX
arch/powerpc/platforms/Kconfig:351: symbol MCU_MPC8349EMITX depends on I2C
This is due to FB_OLPC_DCON selecting I2C instead of depending on it,
so change the select to a dependency.
