[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.
