serial: sh-sci: Use plain struct copy in early_console_setup()

Browse Source 
Using memcpy() prevents the compiler from doing any checking on the
types of the passed pointer parameters.  Copy the structure using struct
assignment instead, to increase type-safety.

No change in generated code on all relevant architectures
(arm/arm64/riscv/sh).
