phy: mediatek: mipi: mt8183: fix minimal supported frequency
The lowest supported clock frequency of the PHY is 125MHz (see also
mtk_mipi_tx_pll_enable()), but the clamping in .round_rate() has the
wrong minimal value, which will make the .enable() op return -EINVAL on
low frequencies. Fix the minimal clamping value.
