Subject: [PATCH 5.12 276/296] scsi: aic7xxx: Restore several defines for aic7xxx firmware build

From: Tom Rix <trix@...hat.com>

[ Upstream commit 7e7606330b167a0ff483fb02caed9267bfab69ee ]

With CONFIG_AIC7XXX_BUILD_FIRMWARE, there is this representative error:

  aicasm: Stopped at file ./drivers/scsi/aic7xxx/aic7xxx.seq,
    line 271 - Undefined symbol MSG_SIMPLE_Q_TAG referenced

MSG_SIMPLE_Q_TAG used to be defined in drivers/scsi/aic7xxx/scsi_message.h
as:

  #define MSG_SIMPLE_Q_TAG	0x20 /* O/O */

The new definition in include/scsi/scsi.h is:

  #define SIMPLE_QUEUE_TAG    0x20

But aicasm can not handle the all the preprocessor directives in scsi.h, so
add MSG_SIMPLE_Q_TAB and other required defines back to scsi_message.h.
