drivers/net/at91_emac.c: Fix GCC 4.6 build warnings

Browse Source 
Fix:
at91_emac.c: In function 'at91emac_phy_init':
at91_emac.c:244:20: warning: variable 'duplex' set but not used
[-Wunused-but-set-variable]
at91_emac.c:244:13: warning: variable 'speed' set but not used
[-Wunused-but-set-variable]

Use new debug_cond() to fix these warnings.  In the result, anumber of
inconsistent printf() formats are detected:

at91_emac.c: In function 'at91emac_read':
at91_emac.c:147:2: warning: format '%x' expects argument of type
'unsigned int', but argument 2 has type 'struct at91_emac_t *'
[-Wformat]
at91_emac.c: In function 'at91emac_write':
at91_emac.c:157:2: warning: format '%x' expects argument of type
'unsigned int', but argument 2 has type 'struct at91_emac_t *'
[-Wformat]
at91_emac.c:157:2: warning: format '%x' expects argument of type
'unsigned int', but argument 4 has type 'short unsigned int *'
[-Wformat]
at91_emac.c: In function 'at91emac_recv':
at91_emac.c:451:3: warning: format '%d' expects argument of type
'int', but argument 2 has type 'long unsigned int' [-Wformat]
at91_emac.c:451:3: warning: format '%x' expects argument of type
'unsigned int', but argument 4 has type 'long unsigned int' [-Wformat]

Fix these, too.
