This patch is relative to D06 SasDxe driver. The SasDxe set a variable to notice this libray. Here Wait for all disk ready for 15S at most.
D06: For using straight-through hard disk backboard, some disk need 15 seconds to ready. Actually, wait less 15 seconds here(minus the time from end of SAS driver to here). For using expander backboard, wait less 6 seconds here(minus the time from end of SAS driver to here).
D03/D05: As Sas driver don't write the SASDiskInfo variable, D03/D05 will break the loop, so it no waiting here.
