commit 6eb5d146 ("ARM: cns3xxx: Use IO memory accessors everywhere")
breaks cns3xxx_pwr_soft_rst_force() function, so that it doesn't write
cleared bit into the register.

This patch fixes the issue by adding the necessary __raw_writel().

Before it isn't too late let's switch to IO memory accessors.
This patch converts all current _REG users and _REG definitions.
There should be no functional changes.

This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.

Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.
