Because uniphier_ehci_reset() is only called from ehci-uniphier.c,
it can be a static function there.

Now UniPhier platform highly depends on Device Tree configuration
(CONFIG_OF_CONTROL is select'ed by Kconfig).  Since the EHCI is only
used on main U-Boot, we can drop platform devices of the EHCI
controllers.  We still keep UART platform devices because they might
be useful for SPL.

We do not have to set the LCR register every time we change the
baud-rate.  We just need to set it up once in the probe function.

For PH1-Pro4, the 8 bit write access to LCR register (offset = 0x11)
is not working correctly.  As a side effect, it also modifies MCR
register (offset = 0x10) and results in unexpected behavior.

Since commit 0e7368c6c426 (kbuild: prepare for moving headers into
mach-*/include/mach), we can replace #include <asm/arch/*.h> with
<mach/*.h> so we do not need to create the symbolic link during the
build.
