we get compilation error for multiple definition of these routines.

On TrimSlice, Tegra's USB1 port may be routed to either an external micro
USB port, or an internal USB->SATA bridge for SSD or HDD. This muxing is
controlled by a GPIO. Whilst not strictly a VBUS GPIO, the TrimSlice
board files caused this GPIO to be set appropriately to enable the SATA
bridge by passing it as the VBUS GPIO to the USB driver. Echo this same
configuration in device tree to enable the SATA bridge.

An alternative might be to implement a full USB bus mux driver. However,
that seems over-complex right now.

Commit 98d9986c (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.

This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.

However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.

Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate.  This is done by
adding a second function that may be used to enable the PHYs.

Marvell engineers tell us:

	It seems that many units use the RUNIT clock.
	SPI, UART, NAND, TWSI, ...
	So it's not possible to clock gate it.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

This enables the new EXYNOS5 platforms in the defconfig, and enables DT
support on EXYNOS4.

Other options enabled: USB host, EXT3/4, regulators and tps65090,
networking and a few of the common usb ethernet adapters as well as the
smsc911x controller used on some boards.

I enabled EFI_PARTITION, since it's used on some filesystem images I'm
using. I didn't see a need to keep Solaris and BSD partition format
still enabled.

Finally, framebuffer console, logo and fonts were enabled.

Note that enabling some of these options introduces build coverage
previously missing, thus introducing a few build errors and warnings
for which fixes have been sent out already.
