ARM: shmobile: lager: fixup IIC2 clock frequency

Current Lager IIC2 is using default clock frequency,
but, ak4643 audio codec chip needs 100kHz
This patch clarifies IIC2 clock frequency as 100kHz.

ARM: shmobile: Add early debugging support using SCIF(A)

Add serial port debug macros for the SCIF(A) serial ports.
This includes all supported shmobile SoCs, except for EMEV2.

The configuration logic (both Kconfig and #ifdef) is more complicated than
one would expect, for several reasons:
  1. Not all SoCs have the same serial devices, and they're not always
     at the same addresses.
  2. There are two different types: SCIF and SCIFA. Fortunately they can
     easily be distinguished by physical address.
  3. Not all boards use the same serial port for the console.
     The defaults correspond to the boards that are supported in
     mainline. If you want to use a different serial port, just change
     the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt.
  4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual
     address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END
     = 0xff000000, and must not conflict with the 2 MiB reserved region
     at PCI_IO_VIRT_BASE = 0xfee00000.
       - On SoCs not using the legacy machine_desc.map_io(),
 debug_ll_io_init() is called by the ARM core code.
       - On SoCs using the legacy machine_desc.map_io(),
 debug_ll_io_init() must be called explicitly. Calls are added
 for r8a7740, r8a7779, sh7372, and sh73a0.

This was derived from the r8a7790 version by Laurent Pinchart.

ARM: shmobile: kzm9g legacy: Set i2c clks_per_count to 2

On sh73a0/kzm9g-legacy, probing of the i2c masters fails with:

    i2c-sh_mobile i2c-sh_mobile.0: timing values out of range: L/H=0x208/0x1bf
    sh_mobile: probe of i2c-sh_mobile.0 failed with error -22

According to the datasheet, the transfer rate is derived from the HP
clock (which runs at 104 MHz) divided by two. Hence
i2c_sh_mobile_platform_data.clks_per_count should be set to two.

Now probing succeeds, and i2c works:

    i2c-sh_mobile i2c-sh_mobile.0: I2C adapter 0 with bus speed 100000 Hz (L/H=0x104/0xe0)

ARM: shmobile: lager: enable USB3.0

Since the PHY of USB3.0 and EHCI/OHCI ch2 are the same, the USB3.0

phy phy-e6590100.usb-phy.3: phy init failed --> -16
xhci-hcd: probe of ee000000.usb failed with error -16

If so, we have to unbind the EHCI/OHCI ch2, and then we have to bind
the USB3.0 driver as the following:

  echo 0000:02:02.0 > /sys/bus/pci/drivers/ehci-pci/unbind

  echo ee000000.usb > /sys/bus/platform/drivers/xhci-hcd/bind

Note that there will be pinctrl-related error messages if both
internal PCI and USB3.0 are enabled but they should be just ignored:

ARM: shmobile: Select CONFIG_ZONE_DMA when CONFIG_ARM_LPAE is enabled

Most IP cores on ARM Renesas platforms can only address 32 bits of
physical memory for DMA. Without CONFIG_ZONE_DMA enabled and with the
recent CMA highmem allocation support, the default CMA zone is reserved
above the 4GiB limit when LPAE is enabled, resulting in various driver
failures.

Fix the problem by selecting CONFIG_ZONE_DMA. Other options to
investigate in the future would be to either enable IOMMU support or use
custom CMA reservations for peripherals not supporting LPAE.

While not a strict dependency, the "[PATCH 0/4] Low/high memory CMA
reservation fixes" series is also required to fix a different but related CMA
allocation problem.
