Subject: serial: sh-sci: Fix up default regtype probing.
X-Git-Tag: firefly_0821_release~3680^2~4217^2~23

serial: sh-sci: Fix up default regtype probing.

Presently the default regtype probing inadvertently bails out due to an
inverted error check. This fixes it up, and gets platforms without
explicit regtype specifications working again.
