Never have "not" in a variable name.  Just make this two functions.

static void vt6655_mac_set_bits(void __iomem *iobase, u32 mask)
static void vt6655_mac_clear_bits(void __iomem *iobase, u32 mask)

Rename "bit_mask" to "mask" or "bits" because bit masks are the only type
of mask that there is in the kernel.
