[SCSI] bfa: Brocade-1860 Fabric Adapter PLL init fixes.

- If flash controller is halted unconditionally, this results in
  illegal write access to flash controller register domain. Since
  flash controller registers are only accessible once s_clk is started
  - added logic to check for WGN status and halt flash controller only
  if it is already running.
- Added check to wait for flash controller halt to be completed before
  proceeding with s_clk/l_clk initializations.
- Removed unnecessary reset logic for PMM 1T memory and moved memory
  initialization after flash access enable.
- Disable Brocade-1860 asic MBOX interrupt before PLL initialization.
- Remove reset enable for S_CLK/L_CLK after both PLL initializations
  are complete.
