The use of the RowOpen/RowHit lambdas to detect the bank state during a RD/WR operation does not consider the Pre-Opened state, specific to LPDDR5. This results in assuming the default case, which provokes an execution error.
This commit fixes this behavior by using custom lambdas for LPDDR5, to include the additional state.

A similar fix was provided by the PSAL-POSTECH group in https://github.com/PSAL-POSTECH/ramulator2, commit bb1d54f.
