Arnd Bergmann 6b5edc71aa x86/olpc: select GPIOLIB_LEGACY
The OLPC GPIO controller sets up a fixed number space that is used
by at least two drivers:

arch/x86/platform/olpc/olpc-xo1-sci.c: In function 'setup_ec_sci':
arch/x86/platform/olpc/olpc-xo1-sci.c:358:13: error: implicit declaration of function 'gpio_request' [-Wimplicit-function-declaration]
  358 |         r = gpio_request(OLPC_GPIO_ECSCI, "OLPC-ECSCI");
      |             ^~~~~~~~~~~~
sound/pci/cs5535audio/cs5535audio_olpc.c: In function 'olpc_analog_input':
sound/pci/cs5535audio/cs5535audio_olpc.c:41:9: error: implicit declaration of function 'gpio_set_value'; did you mean 'gpiod_set_value'? [-Wimplicit-function-declaration]
   41 |         gpio_set_value(OLPC_GPIO_MIC_AC, on);

The AMD Geode platform that this is based on is now marked as
'Orphaned' in Kconfig, and it is likely that there are no XO1
users on modern kernels, but so far there is no consensus on
removing it entirely.

Select CONFIG_GPIOLIB_LEGACY for this platform and make sure the
sound driver portion cannot be compiled without this.
