gpio: Update Kconfig text for GPIO_SYSFS 



This feature is deprecated, it is helpful to inform users about
this. I'm resisting the temptation to add "depends on BROKEN"
to this, but saving that for later.

	  This is mostly useful to work around omissions in a system's

	  kernel support.  Those are common in custom and semicustom

	  hardware assembled using standard kernels with a minimum of

	  custom patches.  In those cases, userspace code may import

	  a given GPIO from the kernel, if no kernel driver requested it.



	  Kernel drivers may also request that a particular GPIO be

	  exported to userspace; this can be useful when debugging.

	  This ABI is deprecated. If you want to use GPIO from userspace,

	  use the character device /dev/gpiochipN with the appropriate

	  ioctl() operations instead. The character device is always

	  available.
