If CONFIG_OF is n, gcc fails:

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.

sizeof(*p) but if patch is otherwise ok (got review/ack) then I can fix
it while applying.

If there is resend, please fix it as well.

With the sizeof(*p) change.
