Tegra30 and Tegra114 are compatible except PLL parameters.

Tested on Tegra30 Cardhu, and Tegra114 Dalmore platforms. All works well.

Signed-off-by: Jim Lin jilin@nvidia.com --- Changes in v2: - Move common definitions into arch-tegra/usb.h and chip specific definitions into arch-tegraXX(X)/usb.h - In ehci-tegra.c, add PLL parameters for Tegra30 and Tegra114. - In ehci-tegra.c, use the port pointed by "nvidia,has-legacy-mode" to know whether we do special handling on Port Reset. - Remove some irrelevant whitespace changes. - Use if-else, instead of goto in ehci-tegra.c init_utmi_usb_controller(). - Use original coding for PTS_MASK in ehci-tegra.c init_utmi_usb_controller(). Reason is that these bits are read-only on Tegra20. Don't need special handling between USB1 and USB3 ports. - Use if-else, instead of goto in ehci-tegra.c board_usb_init(). Changes in v3: - None Changes in v4: - In board.c, add inclusion of asm/arch-tegra/usb.h for build warning. - In ehci-tegra.c, modify board_usb_init to find usb nodes with compatible ID in table fdt_usb_controllers and use matched feature flags later. - In ehci-tegra.c, removing is_T30_compatible and is_T114_compatible variables due to above change. - In ehci-tegra.c, change variable port_clear_csc to port_addr_clear_csc. - In pinmux-config-cardhu.h, chnage GMI_AD13 pinmux state to be OUTPUT in order to be driven HIGH for Beaver board.
