The offset of register DSIM_PLLTMR_REG in Exynos5410 / 5420 / 5440
SoCs is different from the one in Exynos4 SoCs.

In case of Exynos5410 / 5420 / 5440 SoCs, there is no frequency
band bit in DSIM_PLLCTRL_REG, and it uses DSIM_PHYCTRL_REG and
DSIM_PHYTIMING*_REG instead.
So this patch adds driver data to distinguish it.

To support MIPI command mode based I80 interface panel,
FIMD should do followings:
- Sets LCD I80 interface timings configuration.
- Uses "lcd_sys" as an IRQ resource and sets relevant IRQ configuration.
- Sets LCD block configuration for I80 interface.
- Sets ideal(pixel) clock is 2 times faster than the original one
  to generate frame done IRQ prior to the next TE signal.
- Implements trigger feature that transfers image data if there is page
  flip request, and implements TE handler to call trigger function.

This is a temporary solution and should be made by more
generic way.

To support LCD I80 interface, the DSI host should register
TE interrupt handler from the TE GPIO of attached panel.
So the panel generates a tearing effect synchronization signal
then the DSI host calls the CRTC device manager to trigger
to transfer video image.

To support LCD I80 interface, the panel should generate
Tearing Effect synchronization signal between MCU and FB
to display video images.
And the display controller should trigger to transfer
video image at this signal.
So the panel receives the TE IRQ, then calls these handler
chains to notify it to the display controller.

There could be the case that the page flip operation isn't finished correctly
with some abnormal condition such as panel reset. So this patch replaces
wait_event() with wait_event_timeout() to avoid waiting for page flip completion
infinitely.
And clears exynos_crtc->pending_flip in exynos_drm_crtc_page_flip()
when exynos_drm_crtc_mode_set_commit() is failed.

Fix a NULL pointer exception when main exynos drm driver was probed
successfully but no components were added (e.g. by incomplete DTS). In
such case the exynos_drm_load() is never called and drvdata is NULL.

The NULL pointer exception may theoretically also happen as a effect of race between
adding components and main driver: if suspend of the driver happens
before adding components.

Furthermore, as the commit-message states, all 486+ CPUs support the

Regular randconfig nightly testing has detected problems with omapdrm.

omapdrm fails to build when the kernel is built to support 64-bit DMA
addresses and/or 64-bit physical addresses due to an assumption about
the width of these types.

Use %pad to print DMA addresses, rather than %x or %Zx (which is even
more wrong than %x).  Avoid passing a uint32_t pointer into a function
which expects dma_addr_t pointer.

Regular nightly randconfig build testing discovered these warnings:

drivers/gpu/drm/bochs/bochs_drv.c:117:12: warning: 'bochs_pm_resume' defined but not used [-Wunused-function]

Fix these by adding the same condition that SET_SYSTEM_SLEEP_PM_OPS()
uses.
