phy: marvell: a3700: Set USB3 RX wait depending on ref clock
According to specification, CFG_PM_RXDLOZ_WAIT should be set to 0x7 when reference clock is at 25 MHz. The specification (at least the version I have) does not mentoin the setting for 40 MHz reference clock, but Marvell's U-Boot sets 0xC in that case.
