phy: exynos5-usbdrd: Do not depend on Type-C

Older Exynos designs, like Exynos5422, do not have USB Type-C and the
USB DRD PHY does not really need CONFIG_TYPEC for these devices at all.
Incorrectly added optional dependency on CONFIG_TYPEC caused this driver
to be missing for exynos_defconfig and as result Exynos5422-based boards
like Hardkernel Odroid HC1 failed to probe USB.

phy: exynos5-usbdrd: subscribe to orientation notifier if required

gs101's SS phy needs to be configured differently based on the
connector orientation, as the SS link can only be established if the
mux is configured correctly.

The code to handle programming of the mux is in place already, this commit
now adds the missing pieces to subscribe to the Type-C orientation
switch event.

Note that for this all to work we rely on the USB controller
re-initialising us. It should invoke our .exit() upon cable unplug, and
during cable plug we'll receive the orientation event after which we
expect our .init() to be called.

Above reinitialisation happens if the DWC3 controller can enter runtime
suspend automatically. For the DWC3 driver, this is an opt-in:
echo auto > /sys/devices/.../11110000.usb/power/control
Once done, things work as long as the UDC is not bound as otherwise it
stays busy because it doesn't cancel / stop outstanding TRBs. For now
we have to manually unbind the UDC in that case:
echo "" > sys/kernel/config/usb_gadget/.../UDC

Note that if the orientation-switch property is missing from the DT,
the code will behave as before this commit (meaning for gs101 it will
work in SS mode in one orientation only). Other platforms are not
affected either way.

phy: samsung: Merge Kconfig for Exynos5420 and Exynos5250

Exynos5420 variant of USB2 PHY is handled by the same code as the
Exynos5250 one. Introducing a separate Kconfig symbol for it was an
over-engineering, which turned out to cause build break for certain
configurations:

ERROR: modpost: "exynos5420_usb2_phy_config" [drivers/phy/samsung/phy-exynos-usb2.ko] undefined!

Fix this by removing PHY_EXYNOS5420_USB2 symbol and using
PHY_EXYNOS5250_USB2 also for Exynos5420 SoCs.
