[SCSI] arcmsr: 1.20.00.15: add SATA RAID plus other fixes 

Description:
** support ARC1200/1201/1202 SATA RAID adapter, which is named
ACB_ADAPTER_TYPE_B
** modify the arcmsr_pci_slot_reset function
** modify the arcmsr_pci_ers_disconnect_forepart function
** modify the arcmsr_pci_ers_need_reset_forepart function

** for linux standard list
** enable usage of pci message signal interrupt
** follow Randy.Danlup kindness suggestion cleanup this code
**************************************************************************
** 1.20.00.14 05/02/2007 Erich Chen & Nick Cheng
** 1.implement PCI-Express error recovery function and AER capability
** 2.implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096
** if firmware version is newer than 1.42
** 3.modify arcmsr_iop_reset to improve the ability
** 4.modify the ISR, arcmsr_interrupt routine,to prevent the
** inconsistency with sg_mod driver if application directly calls
** the arcmsr driver w/o passing through scsi mid layer
** specially thanks to Yanmin Zhang's openhanded help about AER

This driver supports all of ARECA's SATA RAID controller cards.
This driver supports all of ARECA's SATA/SAS RAID controller cards.
This is an ARECA-maintained driver by Erich Chen.
If you have any problems, please mail to: < erich@areca.com.tw >
If you have any problems, please mail to: <erich@areca.com.tw>.
Areca supports Linux RAID config tools.

Please link <http://www.areca.com.tw>
To compile this driver as a module, choose M here: the
module will be called arcmsr (modprobe arcmsr).

help
The advanced error reporting(AER) capability is "NOT" provided by
ARC1200/1201/1202 SATA RAID controllers cards.
If your card is one of ARC1200/1201/1202, please use the default setting, n.
If your card is other models, you could pick it
on condition that the kernel version is greater than 2.6.19.
This function is maintained driver by Nick Cheng. If you have any
problems or suggestion, you are welcome to contact with <nick.cheng@areca.com.tw>.
