UFS 5.0 / JEDEC 220H introduces the AGGREGATED READ query opcode (0x9),
which retrieves an aggregated data packet from the device in a single
query request. The packet may bundle multiple Descriptors, Attributes
and Flags, each organized as a group with a group header, and is
returned in the Data Segment of the QUERY RESPONSE UPIU.

Because an aggregated data packet can be considerably larger than a
single descriptor (up to 4 KiB rather than the 255-byte descriptor
limit), the response UPIU buffer must be enlarged to hold it. Introduce
ALIGNED_RSP_UPIU_SIZE (4096) for the response_upiu=5B=5D area of the UTP
command descriptor and program the response UPIU length in the UTRD
accordingly.

Teach the BSG raw-UPIU path and the device management command path to
recognize the new opcode so that user space can issue aggregated reads
and receive the returned data segment. Descriptor sizing now honors
QUERY_AGGREGATED_MAX_SIZE for aggregated reads.
