[SCSI] change port speed definitions for scsi_transport_fc

obviously FC Port Speeds in scsi_transport_fc.h are defined according
to FC-HBA:

#define FC_PORTSPEED_1GBIT              1
#define FC_PORTSPEED_2GBIT              2
#define FC_PORTSPEED_10GBIT             4
#define FC_PORTSPEED_4GBIT              8

Problem is, whoever invented FC-HBA did not care about FC-FS or
FC-GS-x. Following FC-FS/FC-GS-x defintions of port speeds would look
like:

1 GBit: 0x0001
2 GBit: 0x0002
4 GBit: 0x0004
10GBit: 0x0008

(and new in FC-LS:
8 Gbit: 0x0010
16GBit: 0x0020)

I really appreciate if scsi_transport_fc.h would define port speeds
according to FC-GS-x/FC-FS. Thus mapping of port speed capabilities to
values defined in scsi_transport_fc.h can be avoided in the LLDD.

Attached is a patch to change the definitions.
