x86: mmconf enable mcfg early

Patch
"x86: validate against ACPI motherboard resources"

changed the mmconf init sequence, and init MMCONF late in acpi_init.

here change it back to old sequence:

 1. check hostbridge in early
 2. check MCFG with e820 in early
 3. if all fail, will check MCFg with acpi _CRS in acpi_init

So we can make MCONF working again when acpi=off is set if hostbridge
support that.
