usb: dwc3: exynos: Add support for Exynos5433 variant with all clocks
DWC3 variant found in Exynos5433 SoCs requires keeping all DRD30/UHOST30
clocks enabled all the time the driver does any access to DWC3 registers,
otherwise external abort happens. So far DWC3 hardware module worked with
samsung,exynos5250-dwusb3 compatible only by luck when built into kernel:
all DRD30 clocks were left enabled by bootloader and later kept enabled
by the DRD PHY driver. However, if one tried to use Exnos DWC3 driver as
a module or performed system suspend/resume cycle, external abort
happened. This patch finally fixes this issue.
