Rename ECAM-specific MMCONF Kconfigs

Browse Source 
Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address
space.  Some platforms have a different way of mapping the PCI config
space to memory.  This patch renames the following configs to
make it clear that these configs are ECAM-specific:

- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

Please refer to CB:57861 "Proposed coreboot Changes" for more
details.
