The init code for UMC (Unified Memory Controller) and PLL has not
been mainlined yet, but U-boot proper should work.

PH1-Pro5 includes a newer version of DDR PHY IP. Some registers
have been added to the reserved areas.

For the same reason as commit d0c47b3ef7 (serial: UniPhier: use
32 bit register access), use "str" instead of "strb" for the LCR
register setting.

In the Linux coding style, it is recommended to include <linux/io.h>
rather than <asm/io.h>. Follow this trend.

Each way of the system cache has 256 entries for PH1-Pro4 and older
SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs. The line
size is still 128 byte. Thus, the way size is 32KB/64KB for old/new
SoCs.
To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the
constant value 32KB. It is large enough for temporary RAM and
should work for all the SoCs of UniPhier family.

This function was intended for MN2WS0235 (what we call PH1-Pro4TV).
On that SoC, MPLL is already running on the power-on reset and it
makes sense to stop the PLL at early boot-up.
On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register,
so this function has no point.

This code is duplicated in ph1-ld4/sg_init.c and ph1-pro4/sg_init.c.
Merge the same code into a new file, memconf.c.
The helper functions no longer have to be placed in the header file.
Also, move them into memconf.c.

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.

Deassert the reset signal and provide the clock for STDMAC core.
This is necessary for the USB 2.0 host controllers.

Since commit 0e7368c6c4 (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.
