Add clock control support for sh7372 CMT hardware blocks.

No upstream sh7372 boards are making use of CMT3 + CMT4,
but the sh7372 hardware happens to come out of reset with
all CMT MSTP clocks _enabled_, so to save power we need
to implement a fix in software to shut down unused clocks.

This patch relies on the recently merged

This patch removes support for the SGX interrupt source in
the sh7372 INTCS controller.

The SGX hardware block included in sh7372 is already hooked
up to the ARM Cortex-A8 core using the INTCA controller,
so SGX users are encouraged to make use of that interrupt
source instead.

Removing support for the SGX interrupt source in INTCS
simplifies the sh7372 power management code by allowing
us to assume that only INTCA needs to be powered on to
operate the SGX hardware.

If the INTCS interrupt source would be kept then the kernel
would be forced to deal with additional dependencies that does
not follow the regular power domain hiearachy. With this
patch in place we can safely power down INTCS while the
SGX is operating.

sh-sci.c sets hardware up and then let the HW do all flow controls.
There is no software code, nor needs to get/set real CTS signal.

But, when turning CRTSCTS on through termios, uart_set_termios() in
serial_core.c checks CTS, and stops TX if it is inactive at the moment.

Because sci_get_mctrl() returns a fixed value DTR|RTS|DSR but CTS,
the sequence
  open -> set CRTSCTS -> write
hit the case and stop working, no more outputs.

This patch makes sci_get_mctrl() report CTS in addition.

According to the SFI specification irq number 0xFF means device has no
interrupt or interrupt attached via GPIO.

Currently, we don't handle this special case and set irq field in
*_board_info structs to 255.  It leads to confusion in some drivers.
Accelerometer driver tries to register interrupt 255, fails and prints
"Cannot get IRQ" to dmesg.

This bug causes the IECSR register clear failure.  In this case, the RETE
(retry error threshold exceeded) interrupt will be generated and cannot be
cleared.  So the related ISR may be called persistently.

The RETE bit in IECSR is cleared by writing a 1 to it.

The previous rtc-s3c had two issues related with its IRQ.

1. Users cannot open rtc multiple times because an open operation
   calls request_irq on the same IRQ.  (e.g., two user processes wants to
   open and read RTC time from rtc-s3c at the same time)

2. If alarm is set and no one has the rtc opened with filesystem
   (either the alarm is set by kernel/boot-loader or user set an alarm and
   closed rtc dev file), the pending bit is not cleared and no further
   interrupt is invoked.  When the alarm is used by the system itself such
   as a resume from suspend-to-RAM or other Low-power modes/idle, this is
   a critical issue.

This patch mitigates these issues by calling request_irq at probe and
free_irq at remove.

Commit 79dfdacc ("memcg: make oom_lock 0 and 1 based rather than
counter") tried to oom lock the hierarchy and roll back upon
encountering an already locked memcg.

The code is confused when it comes to detecting a locked memcg, though,
so it would fail and rollback after locking one memcg and encountering
an unlocked second one.

The result is that oom-locking hierarchies fails unconditionally and
that every oom killer invocation simply goes to sleep on the oom
waitqueue forever.  The tasks practically hang forever without anyone
intervening, possibly holding locks that trip up unrelated tasks, too.
