[PATCH AUTOSEL 5.7 172/388] staging: wfx: avoid compiler warning on empty array

[ Upstream commit 2eeefd3787fdc6319124945d453774be95b97897 ]

When CONFIG_OF is disabled, gcc-9 produces a warning about the
wfx_sdio_of_match[] array having a declaration without a dimension:

drivers/staging/wfx/bus_sdio.c:159:34: error: array 'wfx_sdio_of_match' assumed to have one element [-Werror]
159 | static const struct of_device_id wfx_sdio_of_match[];
| ^~~~~~~~~~~~~~~~~

Move the proper declaration up and out of the #ifdef instead.

Fixes: a7a91ca5a23d ("staging: wfx: add infrastructure for new driver")
