The exynos fimd provides video type selection bits from system register
but exynos3 series don't has it, so needs has_vtsel flag and we can
distinguish whether set video type selection bits.

It's better to be checking whether triggerring in fimd_trigger function.
Also it will return if in triggerring on fimd_te_handler, then it can't
execute remain codes.

The panel power state was initialized by devm_kzalloc() to 0 which means
FB_BLANK_UNBLANK. Request to unblank frame buffer from sysfs was
triggering a call to panel set_brightness(). This lead to starting DSI
transfers on disabled DSI/panel (no calls to exynos_dsi_enable, s6e63j0x03_prepare,
s6e63j0x03_enable)

This patch makes sure for a wait_for_vblank event to be handled
in same period. For this, it adds a new member, triggerred which
means whether trigger request is completed or not since trigger
request.
So if there is a trigger request, update-request, then this patch makes
a wait_for_vblank event to be handled after the trigger request is
completed.

For providing VBLANK information, drm_handle_vblank() should
be called properly, but it is blocked by wait_vsync_event
condition which is set by manager_ops->wait_for_vblank().
So moves it out from wait_vsync_event routine.

This patch fixes the issue that the screen is shared once resume.
The issue could be incurred when overlay registers are updated by
win_commit while transmitting video data.
So this patch makes win_commit function wait for vsync signal
if fimd is still transmitting video data before updating overlay
registers.

The offset of register DSIM_PLLTMR_REG in Exynos5420 is
different from the one in Exynos4 SoC.
In case of Exynos5420 SoC, 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.
