x86/devicetree: Initialize device tree before using it

[ Upstream commit 628df9dc5ad886b0a9b33c75a7b09710eb859ca1 ]

Commit 08d53aa58cb1 added CRC32 calculation in early_init_dt_verify() and
checking in late initcall of_fdt_raw_init(), making early_init_dt_verify()
mandatory.

The required call to early_init_dt_verify() was not added to the
x86-specific implementation, causing failure to create the sysfs entry in
of_fdt_raw_init().

Fixes: 08d53aa58cb1 ("of/fdt: export fdt blob as /sys/firmware/fdt")
