x86/devicetree: Re-enable x86-specific implementation

Fixing x86-specific DT implementation in the kernel allows reusing most of firmware code for SoC that have ARM core replaced with x86, e.g. SC9853i.

Changes since v3:

* Using fdt_totalsize() to get DTB size before remapping instead of setting initial_boot_params and calling of_get_flat_dt_size() before early_init_dt_verify();

* Adding new intel,apic-id property to the documentation.

Changes since v2:

* WARN_ON_ONCE instead of WARN_ON to aviod multiple warnings when APIC ID is missing in CPU device tree nodes

* Switched to Mutt because of white space issues:
"Preformatted" paragraph style does not work in Evolution 3.18.5.2

Changes since first version:

* Splitting a single patch into three parts
