USB: musb: partial DaVinci dm355 support
Partial support for DaVinci DM355, on the EVM board; peripheral
mode should work, once mainline merges DM355 support. Missing:
(a) renumbering the GPIO for DRVVBUS on the DM6446 EVM,
when DAVINCI_N_GPIO increases;
(b) disabling DM355_DEEPSLEEP.DRVVBUS_OVERRIDE so VBUS is
driven according to the ID signal, if cpu_is_..._dm355()
The new PHY control bits are ignored on DM6446.
