EXYNOS5440 includes both OHCI and EHCI usb host controllers.
This patch adds device tree nodes for both of them. And the
EHCI and OHCI controllers on exynos5440 do not need any
explicit phy configuration. So need to assign a different
compatible value for these controllers.

RTC is a basic feature of EXYNOS5440. But it was disabled
by issue that comes from EXYNOS5250. (commit id: 522ccdb6)
That issue only applies to EXYNOS5250 not EXYNOS5440. So,
there is no issue with enabled RTC on EXYNOS5440. This
change was tested on EXYNOS5440.

 "This branch contains a set of straight forward bug fixes to the

* tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux:

  irqdomain: document the simple domain first_irq
  kernel/irq/irqdomain.c: before use 'irq_data', need check it whether valid.
  irqdomain: export irq_domain_add_simple

The irqdomain core will report a log message for any attempted map call
that fails unless the error code is -EPERM. This patch changes the
Versatile irq controller drivers to use -EPERM because it is normal for
a subset of the IRQ inputs to be marked as reserved on the various
Versatile platforms.
