I plan to move these tow flags to Acpi62.h, and optimize the code for Flags.

I plan to move these two macro to Acpi62.h.

While your at it the write policy and cache type should also probably be 
defined and used in your init routing
I don't really understand the mean above.

I compare those macro of the ArmLibPrivae.h and these two struct. Those macro 
are not equivalent to
these two struct, like offset of Associativity is 3 in CCSIDR_DATA (as 
DDI0487A_h_armv8_arm.pdf),
but 15 in ArmLibPrivae.h, and miss NumSets in ArmLibPrivae.h, and so on.

I have replace it with struct in Acpi62.h.
