Subject: [PATCH v2 07/14] [net-next] ax88796: export ax_NS8390_init() hook

From: Michael Schmitz <schmitzmic@...il.com>

The block I/O code for the new X-Surf 100 ax88796 driver needs
ax_NS8390_init() for error fixup in its block_output function.

Export this static function through the ax_NS8390_reinit()
wrapper so we can lose the lib8380.c include in the X-Surf 100
driver.

[arnd: add the declaration in the header to avoid a
 -Wmissing-prototypes warning]
Fixes: 861928f4e60e826c ("net-next: New ax88796 platform
driver for Amiga X-Surf 100 Zorro board (m68k)")
