Geert Uytterhoeven f808b86507 m68k/hp300: Export hp300_ledstate
The accidental loss of CONFIG_DIO in commit
0e152d8050 ("m68k: reorganize Kconfig options
to improve mmu/non-mmu selections") exposed a missing symbol export in
m68k allmodconfig.  If CONFIG_HP300=y but CONFIG_HPLANCE (which is bool,
and depends on CONFIG_DIO) is not set, and CONFIG_MVME147=y and
CONFIG_MVME147_NET=m, 7990.c is compiled as a module, giving:

ERROR: "ledstate" [drivers/net/ethernet/amd/7990.ko] undefined!

Add the missing export, and rename ledstate to hp300_ledstate while we're
at it, as it's a too generic name.
