net: stmmac: use correct type for tx_lpi_timer

Browse source 
The ethtool interface uses u32 for tx_lpi_timer, and so does phylib.
Use u32 to store this internally within stmmac rather than "int"
which could misinterpret large values.

Correct "value" in dwmac4_set_eee_lpi_entry_timer() to use u32
rather than int, which is derived from tx_lpi_timer. Even though this
path won't be used with values larger than STMMAC_ET_MAX, this brings
consistency of type usage to the stmmac code for this variable.

We leave eee_timer unchanged for now, with the assumption that values
up to INT_MAX will safely fit in a u32.
