Expand the ufshcd_device_init(hba, true) call and remove all code that
depends on init_dev_params == false. This change prepares for combining
the two scsi_add_host() calls.

I have similar comment as in previous patch #6. This patch probably
changed the print. In the original code, it prints the time spent in
probe_hba(), but here it prints some part of the time spent in
ufshcd_init(). There will be some trace prints during init, but the data
it prints would have inconsistent meaning.
if (err)
goto out_disable;
