hwmon: VRM is not written to registers

What was true of reading the VRM value is also true of writing it: not
being a register value, it doesn't need hardware access, so we don't
need a reference to the i2c client. This allows for a minor code
cleanup. As gcc appears to be smart enough to simplify the generated
code by itself, this cleanup only affects the source code, the
generated binaries are unchanged.
