ACPICA: iASL compiler: allow compilation of externals with paths that refer to existing names

ACPICA commit 9a252114197409290813bee570e9d53c22b99d32

This change allows compilation of code like the following:

definition_block (...)
{
    External (ABCD.EFGH)
    Device (ABCD)
    {
        Name (IJLK,0)
    }
}

but does not allow compilation of code like the following:

definition_block (...)
{
    External (ABCD)
    Device (ABCD)
    {
        Name (EFGH,0)
    }
}
