serial: UniPhier: borrow macros from linux/serial_reg.h

The same bit-field macros are defined in include/linux/serial_reg.h
so let's include it and delete duplicated defines.

Also, remove unnecessary inclusion of <common.h>.

ARM: UniPhier: reset on-board devices on start-up

If a support card is attached to the main board, the on-board
SMSC9118 LAN controller is available.  It must be kept in reset
state for a while on start-up.

When the board is kicked via a debbuger rather than pushing the
hardware reset button, on-board chips are not reset; in this case
the reset signals should be asserted by software.

ARM: UniPhier: add MIO register file

This commit adds register defines of MIO (Media I/O) block
of UniPhier platform.  This file is necessary to control
the reset signals of the USB cores.

usb: UniPhier: add UniPhier on-chip EHCI host driver support

Support EHCI host driver used on Panasonic UniPhier platform.
Since Device Tree is not supported on UniPhier yet, the base address
of USB cores are passed from board files (platdevice.c).

TODO for me:
Move the base address to device trees.

ARM: UniPhier: add set_pinsel macro for use in assembly code

The function sg_set_pinsel is useful for switching I/O pins
but it can be only used in C code.  This commit adds a simple
macro that is available in asm code.

ARM: UniPhier: decrease pre-reloc malloc area size

In the current implementation of the boot sequence of UniPhier
platform, 32KB temporary RAM is available before relocation.
The malloc area and the stack shares the 32KB area.

With CONFIG_SYS_MALLOC_F_LEN set to 0x7000 (28KB), only 0x1000 (4KB)
is left for the stack.  In some use cases, the system hangs up
with stack over-flow.

Even with driver-model UART enabled, the malloc area of 0x2000 (8KB)
should be enough.

ARM: UniPhier: consolidate board_postclk_init() function

This commit merges
  arch/arm/cpu/armv7/uniphier/ph1-*/board_postclk_init.c
to
  arch/arm/cpu/armv7/uniphier/board_postclk_init.c

Because PH1-Pro4 does not have the BCU block, add __weak to
bcu_init().

ARM: UniPhier: call pin_init() also in the normal boot

CONFIG_UNIPHIER_SERIAL has been moved to Kconfig and
it is defined in ./.config but not in spl/.config,
so pin_init() should be called from the normal image
so that UART works correctly.
