phy: renesas: rcar-gen3-usb2: store drvdata pointer in channel

Browse Source 
Store the SoC-specific driver data pointer (struct rcar_gen3_phy_drv_data)
directly in struct rcar_gen3_chan instead of copying individual flags into
separate channel members.

Obtain the drvdata with of_device_get_match_data() in probe and assign it
to channel->phy_data. Update all call sites to reference
`channel->phy_data->*` for SoC-specific behaviour (for example no_adp_ctrl
and utmi_ctrl). Remove the redundant soc_no_adp_ctrl and utmi_ctrl fields
from struct rcar_gen3_chan.

This simplifies the probe path, reduces duplication, and makes it easier
to extend the driver with additional platform-specific fields in the
future.
