net: phy: make phy_device members pause and asym_pause bitfield bits

We can reduce the size of struct phy_device a little by switching
the type of members pause and asym_pause from int to a single bit.
As C99 is supported now, we can use type bool for the bitfield members,
what provides us with the benefit of the usual implicit bool conversions.
