The problem is that select and depend don't interact because Kconfig doesn't
have a SAT solver, so depend picks up dependencies and select does onward
selects, but select doesn't pick up dependencies. To fix this, we need to add
the correct dependencies to the MPT2SAS option like this.

The mpt2sas driver was recently folded into mpt3sas to reduce code
duplication.
To avoid problems for people that only have CONFIG_SCSI_MPT2SAS in their
.config we introduce a dummy option that will select MPT3SAS if MPT2SAS
was previously enabled.
This is a temporary measure and we will deprecate this config option in
4.6.
