scsi: lpfc: Rework lpfc Kconfig for NVME options

Browse Source 
Reworked Kconfig so that lfpc only requires the scsi stack.
NVME Initiator and NVME Target support can be enabled if
the other NVMe subsystems have been enabled.

This lpfc driver supports the Emulex LightPulse

This makes debugging information from the lpfc driver
available via the debugfs filesystem.

This enables NVME Initiator support in the Emulex lpfc driver.

---help---
This enables NVME Target support in the Emulex lpfc driver.
Target enablement must still be enabled on a per adapter
basis by module parameters.
