[ Upstream commit 06f76e464ac81c6915430b7155769ea4ef16efe4 ]
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.
