Fix Ping Pong and HOMER addresses, usign new P9 pba_region default value.

The new P9 pba_region field in the PBA_MODE register is now 0b10
contrary to the P8 pba_region setting of 0b00.

Addresses have been corrected for Ping Pong communications,
HOMER Host Data, Sapphire Table, and HTMGT send and receive Buffers.

Replaced Sapphire legacy term with OPAL.

Defined COMMON_BASE_ADDRESS, and offset addresses relative to it.

modified HOMER_HD_OFFSET, OCC_HTMGT_CMD_OFFSET_HOMER,
OCC_HTMGT_RSP_OFFSET_HOMER, and OPAL_OFFSET_HOMER according
to new P9 specifications.
