scsi: lpfc: Properly set WC for DPP mapping
Using set_memory_wc() to enable write-combining for the DPP portion of
the MMIO mapping is wrong as set_memory_*() is meant to operate on RAM
only, not MMIO mappings. In fact, as used currently triggers a BUG_ON()
with enabled CONFIG_DEBUG_VIRTUAL.
Simply map the DPP region separately and in addition to the already
existing mappings, avoiding any possible negative side effects for
these.
