From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
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.
Fixes: dd076cffb8cd ("serial: sh-sci: Fix init data attribute for struct 'port_cfg'")
