tcl: add a configuration file for Nuvoton M541 & NUC442/472 series

This patch is picked from the tcl part of OpenOCD-Nuvoton's commit
("flash: supported Nuvoton M4 series. jtag: Used HW reset instead of
auto reset. tcl: added a configuration file for Nuvoton M4 series.") [1]
to support the communication with Nuvoton's Cortex-M4 chips: M541 &
NUC442/472 series.

This patch has been tested with Nuvoton's NuTiny-SDK-NUC472 development
board [2].

The code comes from the commit basically. Jian-Hong Pan tweaked for the
compatibility with current OpenOCD. So, leave the author as Zale Yu.
