Subject: [PATCH v2] memory: omap-gpmc: Fix build error without CONFIG_OF

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 to fix this.

Fixes: a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
