[U-Boot] [PATCH] net: dm9000x: re-add casts to I/O pointers to fix gcc warnings
The DM9000 in/out helper functions were casting the register address when it was accessing things directly (pre commit a45dde2293c816138e53c). But when it was changed to using the in/out helpers, those casts were dropped because those functions don't take pointers. Even more recently, those functions were then changed to use the read/write helpers, but the casts were not re-added. This is necessary because the read/write helpers do take pointers. Otherwise we get a lot of warnings like: dm9000x.c: In function 'dm9000_inblk_8bit': dm9000x.c:172: warning: passing argument 1 of 'readb' makes pointer from integer without a cast
