net: phy: nxp-c45-tja11xx: fix unsigned long multiplication overflow

commit bdaaecc127d471c422ee9e994978617c8aa79e1e upstream.

Any multiplication between GENMASK(31, 0) and a number bigger than 1
will be truncated because of the overflow, if the size of unsigned long
is 32 bits.

Replaced GENMASK with GENMASK_ULL to make sure that multiplication will
be between 64 bits values.
