net: stmmac: use BIT_U32() and GENMASK_U32() for PCS registers

stmmac registers a 32-bit. u32 is unsigned int. The use of BIT() and
GENMASK() leads to integer promotion to unsigned long in expressions
such as:

	u32 old = foo;

	dev_info(dev, "%08x %08x\n", old, old & BIT(1));

resulting in arg2 being accepted as compatible with the format string
and arg3 warning that the argument does not match (because the former
is unsigned int, and the latter is unsigned long.)

Fix this by defining 32-bit register bits using BIT_U32() and
GENMASK_U32() macros.
