phy: exynos5-usbdrd: support Exynos USBDRD 3.2 4nm controller

Add support for the Exynos USB 3.2 DRD 4nm controller. It's used in
recent 4nm SoCs like Exynos2200 and Exynos2400.

This device consists of 3 underlying and independent phys: SEC link
control phy, Synopsys eUSB 2.0 and Synopsys USBDP/SS combophy. Unlike
older device designs, where the internal phy blocks were all IP of
Samsung, Synopsys phys are present. This means that the link controller
is now mapped differently to account for missing bits and registers.
The Synopsys phys also have separate register bases.

As there are non-SEC PHYs present now, it doesn't make much sense to
implement them in this driver. They are expected to be configured
by external drivers, so pass phandles to them. USBDRD3.2 link controller
set up is still required beforehand.

This commit adds the necessary changes for USB HS to work. USB SS and
DisplayPort are out of scope in this commit and will be introduced
in the future.
