net: smc91x: Fix m68k kernel compilation for ColdFire CPU
Compiling the m68k kernel with support for the ColdFire CPU family fails
with the following error:
In file included from drivers/net/ethernet/smsc/smc91x.c:80:
drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_reset’:
drivers/net/ethernet/smsc/smc91x.h:160:40: error: implicit declaration of function ‘_swapw’; did you mean ‘swap’? [-Werror=implicit-function-declaration]
160 | #define SMC_outw(lp, v, a, r) writew(_swapw(v), (a) + (r))
| ^~~~~~
drivers/net/ethernet/smsc/smc91x.h:904:25: note: in expansion of macro ‘SMC_outw’
904 | SMC_outw(lp, x, ioaddr, BANK_SELECT); \

drivers/net/ethernet/smsc/smc91x.c:250:9: note: in expansion of macro ‘SMC_SELECT_BANK’
250 | SMC_SELECT_BANK(lp, 2);
| ^~~~~~~~~~~~~~~
cc1: some warnings being treated as errors
The function _swapw() was removed in commit d97cf70af097 ("m68k: use
asm-generic/io.h for non-MMU io access functions"), but is still used in
drivers/net/ethernet/smsc/smc91x.h.
Use ioread16be() and iowrite16be() to resolve the error.
