acpi/acpi.c: Accomodate 64bit MMCONF base in MCFG table
Allow the use of 64bit MMCONF base in MCFG table.
Previously only 32 bits were utilized for MMCONF base, while the
remaining 32bits were reserved & held value of zero as evident from MCFG
table disassembly. This commit entails updating the 'base_address' field
in the 'mmconfig' structure to 64 bits and removing the 'base_reserved'
field.
TEST=Confirmed the functionality of the 64bit MMCONF base in the MCFG
table disassembly below
