Reworked the 5V vs. 6V transistor handling in magic for GF180MCU
to be a bit more consistent with other tools (namely klayout,
but also with layout submitted to GF and checked by GF). The
5V and 6V FET devices were separated into two types "mvnfet"
("mvpfet") and "hvnfet" ("hvpfet"), respectively, where previously
there was only one type. The FET5VDEF mask (112:1, or V5_XTOR)
is applied to the "mv" types and not to the "hv" types. The
generated cells have been modified to match this, with the
correct gate type being applied for "5V" vs. "6V" types. The
device DRC for minimum channel length is applied separately.
