efi: Make EFI_MEMORY_ATTRIBUTES_TABLE initialization common across al…

…l architectures

Since EFI_PROPERTIES_TABLE and EFI_MEMORY_ATTRIBUTES_TABLE deal with
updating memory region attributes, it makes sense to call
EFI_MEMORY_ATTRIBUTES_TABLE initialization function from the same place
as EFI_PROPERTIES_TABLE. This also moves the EFI_MEMORY_ATTRIBUTES_TABLE
initialization code to a more generic efi initialization path rather
than ARM specific efi initialization. This is important because
EFI_MEMORY_ATTRIBUTES_TABLE will be supported by x86 as well.
