[ Upstream commit 553f7ac78fbb41b2c93ab9b9d78e42274d27daa9 ]
The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK.
However, when this protection was added, it was missed that SuperH no
longer defines an EARLY_PRINTK config symbol since commit
e76fe57447 ("sh: Remove old early serial console code V2"), so
BIOS earlyprintk can no longer be used.
Fix this by reviving the EARLY_PRINTK config symbol.
Fixes: d0380e6c3c ("early_printk: consolidate random copies of identical code")
