[PATCH v4 06/31] elx: libefc_sli: bmbx routines and SLI config commands

[James Smart <james.smart@broadcom.com>]

[-- Attachment #1: Type: text/plain, Size: 31365 bytes --]

This patch continues the libefc_sli SLI-4 library population.

This patch adds routines to create mailbox commands used during
adapter initialization and adds APIs to issue mailbox commands to the
adapter through the bootstrap mailbox register.

v4:
  Changed bmbx_wait and fw_ready routines to use usleep_range and
     time_before apis
  Removed size input for all the cmds as its fixed to SLI4_BMBX_SIZE.
