Move subsections inside the section

When I updated the VMAX Cinder driver doc, I put subsections
outside of the section that referenced them. The published doc
doesn't look right. This patch is to move subsections inside
the section.

Here is how the VMAX doc looks like currently:

http://docs.openstack.org/trunk/config-reference/content/emc-vmax-driver.html

The following links are displayed at the top of the doc:

System requirements
Supported operations
Install the python-pywbem package
Set up SMI-S
cinder.conf configuration file
cinder_emc_config_CONF_GROUP_ISCSI.xml configuration file
FC Zoning with VMAX
iSCSI with VMAX
Set up the VMAX drivers
VMAX masking view and group naming info
Concatenated or striped volumes

As shown above, links to the sub-sections inside the "Set up the VMAX
drivers" section also showed up in the beginning.

The purpose of this patch is to hide the sub-sections inside the
"Set up the VMAX drivers" section, so that only the following links
showing up in the beginning of the doc:

System requirements
Supported operations
Set up the VMAX drivers
VMAX masking view and group naming info
Concatenated or striped volumes
