serial: sh-sci: Drop __initdata macro for port_cfg
commit eaeee4225dba30bef4d424bdf134a07b7f423e8b upstream.
The port_cfg object is used by serial_console_write(), which serves as
the write function for the earlycon device. Marking port_cfg as __initdata
causes it to be freed after kernel initialization, resulting in earlycon
becoming unavailable thereafter. Remove the __initdata macro from port_cfg
to resolve this issue.
