[ Upstream commit 13d029ee51da365aa9c859db0c7395129252bde8 ]
If CONFIG_OF is n, gcc fails:
drivers/memory/omap-gpmc.o: In function `gpmc_omap_onenand_set_timings':
omap-gpmc.c:(.text+0x2a88): undefined reference to `gpmc_read_settings_dt'
Add gpmc_read_settings_dt() helper function, which zero the gpmc_settings
so the caller doesn't proceed with random/invalid settings.
Fixes: a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
