[PATCH 2/4] ARM: dts: imx: Pick safe DRAM size on failure on Data Modul i.MX8M Mini/Plus eDM SBC

[Marek Vasut]

In case gpio_request_list_by_name_nodev() in board dmo_get_memcfg()
returns error code, pick a safe default DRAM configuration instead
of bailing out with some sort of hang() or panic(). The BIT(2)|BIT(0)
strap option is the lowest known option of 2 GiB , use that.
