x86/geode: use PROPERTY_ENTRY_REF for GPIO properties

Now that the PROPERTY_ENTRY_REF macro can accept a pointer to struct software_node_ref_args directly, we don't need to use the more cumbersome PROPERTY_ENTRY_REF_ARRAY_LEN(..., 1) variant.

---

This patch was originally posted as patch 4/4 of the "Fix handling of GPIO keys and LEDs on geode" series [1].

From that series:
- Patch 1/4 was applied to tip:x86/urgent as commit b981e9e94c68 ("x86/platform/geode: Fix on-stack property data use-after-return bug").
- Patch 2/4 was merged through the driver-core tree as commit fe221742e388 ("software node: allow passing reference args to PROPERTY_ENTRY_REF()").
- Patch 3/4 (stack check in software_node_register()) has been dropped due to limitations of object_is_on_stack() with CONFIG_VMAP_STACK.

Now that commit fe221742e388 is in mainline, resending patch 4/4 as a standalone cleanup rebased onto current upstream.
