ram: renesas: dbsc5: Fix DBTR11 calculation

Reinstate missing increment by two in DBTR11 calculation based
on the original DBSC5 initialization code rev.0.80. The original
code did ... ODTLon - (js2[JS2_tODTon_min] - 1) + 1 , which was
incorrectly converted into ODTLon - js2[JS2_tODTon_min], but
should have been converted to ODTLon - js2[JS2_tODTon_min] + 2.
Add the missing +2 .
