Hi Daejun,
If you are about to push Ver.27, please hold on. I run into OCP issues
on VCCQ every time after apply this patch. The issue can be work around
by disabling runtime PM. Before you or we figure out where the BUG is,
it is pointless to push next version.

In the case of Read (<= 32KB) is supported as single HPB read.
In the case of Read (36KB ~ 512KB) is supported by as a combination of
write buffer command and HPB read command to deliver more PPN.
