HV: set default MCFG base for generic board

Browse Source 
On most board the MCFG base is set to 0xe0000000, so modify this value in
platform_acpi_info.h for generic boards;

The description of ACPI_PARSE_ENABLED is modified also to match its usage.

Tracked-On: #4157

Whether to parse the ACPI tables at runtime. Platform specific ACPI info may be retrieved thru boot-time parse
of ACPI table, or thru parse of off-line tool. This option enables
the boot-time parse of ACPI table, and overwrite the information
