[Elite-II] pin header P9 description

[jakec64]

Could we please get pin header P9 description in to the manual if this is used for ARMSID additional addressing, similar as U64E had the P7?

Here is screen capture from ARMSID manual how to connect the additional addressing SID A[5..9] line to P7 on U64E

we would need something similar for U64E2, since P9 does not have silkscreen prints or any description
