Always use CS0 shadow area for NOR flash instead of regular CS0
memory area on Mackerel.

When booting from CS0 NOR Flash the regular CS0 memory area is
available, but when booting via USB the MASK ROM gets mapped to
0x0 which gets in the way for the NOR Flash. Always using CS0
shadow area works well for both NOR Flash boot and USB boot.

This change adds support for the sh7372 A4R power domain.

The sh7372 A4R hardware power domain contains the
SH CPU Core and a set of I/O devices including
multimedia accelerators and I2C controllers.

One special case about A4R is the INTCS interrupt
controller that needs to be saved and restored to
keep working as expected. Also the LCDC hardware
blocks are in a different hardware power domain
but have their IRQs routed only through INTCS. So
as long as LCDCs are active we cannot power down
INTCS because that would risk losing interrupts.

This change adds support for the sh7372 A3SP power domain.

The sh7372 A3SP hardware power domain contains a
wide range of I/O devices. The list of I/O devices
include SCIF serial ports, DMA Engine hardware,
SD and MMC controller hardware, USB controllers
and I2C master controllers.

This patch adds the A3SP low level code which
powers the hardware power domain on and off. It
also ties in platform devices to the pm domain
support code.

It is worth noting that the serial console is
hooked up to SCIFA0 on most sh7372 boards, and
the SCIFA0 port is included in the A3SP hardware
power domain. For this reason we cannot output
debug messages from the low level power control
code in the case of A3SP.

QoS support is needed in drivers before we can
enable the A3SP power control on the fly.

Associate the HDMI clock together with LCDC1 on sh7372.

Without this patch Suspend-to-RAM hangs on the boards
AP4EVB and Mackerel. The code hangs in the LCDC driver
where the software is waiting forever for the hardware to
power down. By explicitly associating the HDMI clock with
LCDC1 we can make sure the HDMI clock is enabled using
Runtime PM whenever the driver is accessing the hardware.

This HDMI and LCDC1 dependency is documented in the sh7372
data sheet. Older kernels did work as expected but the
recently merged (3.1-rc)

 794d78fe drivers: sh: late disabling of clocks V2

introduced code to turn off clocks lacking software reference
which happens to include the HDMI clock that is needed by
LCDC1 to operate as expected.
