For dwmac4, GMAC_INT_DEFAULT_ENABLE already includes GMAC_INT_PMT_EN, so it is redundant to check if hw->pmt is set, and if so, setting the bit again.
For dwmac1000, GMAC_INT_DEFAULT_MASK does not include GMAC_INT_DISABLE_PMT, so it is redundant to check if hw->pmt is set, and if so, clearing an already cleared bit.
Improve code readability by removing this redundant code.
