There shouldn't be any restriction of the descriptor size
(not the descriptor id for that matter) up to QUERY_DESC_MAX_SIZE.
According to the spec, the caller can use any descriptor size,
and it is up to the device to return the actual size.
Therefore there shouldn't be any sizes hardcoded in the kernel,
nor any need to cache it, hence ufshcd_map_desc_id_to_length function is
redundant. Always read the descriptors with QUERY_DESC_MAX_SIZE size.
