arch/x86/Kconfig: introduce RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT

Since also some AMD CPUs have reserved physical address bits that can't
be used as normal address bits, introduce the
RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT Kconfig option which gets
selected by CPU_INTEL_COMMON, and use the new common option to configure
if the specific SoC/CPU code implements get_reserved_phys_addr_bits or
if the default of this returning 0 is used instead.
