scsi: ufs: core: Add get_hba_nortt callback for vendor-specific RTT capability

Browse source

The number of outstanding RTTs read from host controller capability
register is problematic on some platforms. Add a new vendor callback
get_hba_nortt() to allow platform vendors to override the default RTT
capability value with platform-specific handling.

This patch keeps max_num_rtt field for bisectability and will be removed in
a later patch once all platforms are migrated.
