A few typos have been discovered both in the specs in and our code.
This patch fixes them.
Also use lpphy_op_switch_channel consistently, and make all callers
print its return value for easier debugging.

I think using a forward declaration is justified in this case;
as avoiding the forward decl would require moving around huge
blocks of code, completely breaking any logical ordering.
