Add Lager board code to check the PWEN GPIO signal and refuse to
allow probe of the USBHS driver in case of DIP misconfiguration.

For correct operation Lager DIP switches SW5 and SW6 shall be
configured in 2-3 position to enable USB Function support.

If the DIP switch is configured incorrectly then the user can
simply adjust the hardware and either reboot or use the bind interface
to try to probe again:

Remove ifdefs to make the Lager USBHS device always present.
This makes it more like other devices, no need to be special.

Also, these ifdefs by themselves do not hurt much, but combined
with USB Host device ifdefs that were proposed earlier we could
basically end up with a kernel that drives VBUS incorrectly
depending on the kernel configuration - lets not do that.

Currently on the Lager board NFS timeouts/delays are seen when booting.  That
turned out to happen because the SoC's ETH_LINK signal turns on and off after
each packet.  It is connected to Micrel KSZ8041 PHY's LED0 signal. Ether LEDs
on the Lager board are named LINK and ACTIVE which corresponds to non-default
01 setting of the PHY control register 1 bits 14-15. The 'sh_eth' driver resets
the PHY when opening the network device, so we have to set the mentioned bits
back to 01 from the default 00 value which causes bouncing of ETH_LINK.  That
can be achieved using the PHY platform fixup mechanism if we also modify the
driver to use it..

When the gpio-keys device is registered using
platform_device_register_data() the platform data argument,
lager_keys_pdata is duplicated and thus should be marked as __initdata
to avoid wasting memory. However, this is not true of gpio_buttons,
a reference to it rather than its value is duplicated when lager_keys_pdata
is duplicated.

This avoids accessing freed memory if gpio-key events occur
after unused kernel memory is freed late in the kernel's boot.

This but was added when support for gpio-keys was added to lager
in c3842e4f
("ARM: shmobile: lager: support GPIO switches") which was included
in v3.11-rc1.
