This patch adds the struct of reading AOSP vendor capabilities.
New capabilities are added incrementally. Note that the
version_supported octets will be used to determine whether a
capability has been defined for the version.
Signed-off-by: Joseph Hwang <josephsih@xxxxxxxxxxxx>

Changes in v5:
- This is a new patch.
- Add struct aosp_rp_le_get_vendor_capabilities so that next patch
can determine whether a particular capability is supported or not.
