[PATCH edk2-platforms v5 09/28] Silicon/Hisilicon/D06: Wait for all disk ready

[Ming Huang <ming.huang@linaro.org>]

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 install PLATFORM_SAS_NOTIFY Protocol, D03/D05
will skip waiting here.
