CDD: Clarify that /sdcard can share storage with /data
Section: 7.6.2. Application Shared Storage

Some device implementations share the internal physical storage
space across both /data and /sdcard to meet the minimum space
requirements for each storage partition, while it is NOT a
RECOMMENDED configuration, this is still meeting the REQUIRED
requirements.
