[PATCH] RX removed control register cpen

[PATCH] RX removed control register cpen

[Darius Galis]

Hello,

The following patch removes the CTRLREG_CPEN register variable.
According to the RX software manual: https://www.renesas.com/cn/en/doc/products/mpumcu/doc/rx_family/r01us0316ej0100-rxv3sm.pdf
there is no control register called cpen.

Regression test is OK, without additional fails, and was tested with the
following command:

make -k check-gcc RUNTESTFLAGS=--target_board=rx-sim

Please let me know if this is OK, Thank you!
Darius

THanks.  I verified that the CPEN register was removed in 2009.  Installed on the
trunk.
