drivers/rtc/rtc-s3c.c: fix no occurrence of alarm interrupt
The driver does not generate an alarm interrupt even though a time for
an alarm is set.
This results from disabling rtc_clk after setting the alarm time.
To generate an alarm interrupt the driver should maintain its enabled
state for rtc_clk the until alarm interrupt occurs. This patch permits
generation of an alarm interrupt.

drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq.
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.

ARM: EXYNOS4: Fixed OHCI/EHCI suspend/resume.
Since now phy controller initialization will not control
usb host clock, individual driver has to take care for
clock gating.

ARM: EXYNOS4: Removed host clock handling and code rework.
1: Since USB host clock handling should be done in driver code
removed that part of code from PHY initialization.
2: Added support to track usage of USB PHY controller.
3: Renamed phy init and exit functions.

ARM: EXYNOS4: Fixed USB OHCI shutdown and suspend hang issue.
It has been observed that during system reboot or suspend/resume system
hangs. Further debugging showed that during shutdown/suspend call OHCI
driver was not able to access any of OHCI registers failing which it was hanging.
As after observing idle condition over the bus OHCI host core controller (HW)
is turning off 12 and 48MHz clocks internally, and since during shutdown/suspend these clocks
are OFF driver is not able to access any of OHCI registers. So as per guidlines given
on data-sheet and Synopsys website, we need to manually enable to clocks for completion
of ohci shutdown/suspend function.

Use macro for jiffies conversion
HZ is not the same on all systems. Use a macro to get the correct number
of jiffies.
