DynamicTablesPkg: Correct _PSD package format
The _PSD structure should have nested packages.
The current implementation generates
Name (_PSD, Package()
{
NumEntries // Integer
Revision // Integer (BYTE)
Domain // Integer (DWORD)
CoordType // Integer (DWORD)
NumProcessors // Integer (DWORD)
})
when this should be
Name (_PSD, Package()
{
Package()
{
NumEntries // Integer
Revision // Integer (BYTE)
Domain // Integer (DWORD)
CoordType // Integer (DWORD)
NumProcessors // Integer (DWORD)
}
})
