ata: libata-core: Allow command duration limits detection for ACS-4 drives

Browse Source 
commit c0297e7dd50795d559f3534887a6de1756b35d0f upstream.

Even though the command duration limits (CDL) feature was first added
in ACS-5 (major version 12), there are some ACS-4 (major version 11)
drives that implement CDL as well.

IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages
are mandatory in the ACS-4 standard so it should be safe to read these
log pages on older drives implementing the ACS-4 standard.
