net: via-rhine: Drop revision property, use quirks instead
This adds two new flags to quirks and thus removes the need to carry
revision in rhine_private. As a result, the init logic is simplified
a bit.
This also fixes a compiler warning in OF code on 64bit due to pointer
casting:
drivers/net/ethernet/via/via-rhine.c: In function ‘rhine_init_one_platform’:
drivers/net/ethernet/via/via-rhine.c:1132:13: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
revision = (u32)match->data;
^
That code was added in commit 2d283862dc
("net: via-rhine: add OF bus binding").
Tested in platform configuration on a VIA WM8950 APC Rock board.
