phy: fsl-imx8mq-usb: fix phy_tx_vboost_level_from_property()

The description of TX_VBOOST_LVL is wrong in register PHY_CTRL3
bit[31:29].

The updated description as below:
011: Corresponds to a launch amplitude of 0.844 V.
100: Corresponds to a launch amplitude of 1.008 V.
101: Corresponds to a launch amplitude of 1.156 V.

This will fix the parsing function
phy_tx_vboost_level_from_property() to return correct value.
