the freed memory lead to iommu pagefault. so we add this reset to workaround.

Because when enable uboot logo display, vop_crtc_enable() will not be
called when power on, this will lead to some vop initial like
axi channel and some debug irq will not be enabled. so we move some
config to vop_initial() and call from vop_crtc_loader_protect().

If hdmi is enabled in uboot and pluged out when booting kernel,
the hdmi phy is still enabled. It's better to disable it to
match the real status.

Under following processes, rxsense will be not match the real
signal status.
1. HDMI plug in, irq is triggered.
2. HDMI irq is mute in dw_hdmi_hardirq, bring up dw_hdmi_irq.
3. For HDMI connection is not stable, phy_stat read in
dw_hdmi_irq may be zero, then hdmi->rxsense will be false.
4. Connection fallback to stable, but dw_hdmi_irq had not
unmute the irq, irq is not triggered again, and hdmi->rxsense
keep false.
5. repo_hpd_event inform HDMI is pluggned in, dw_hdmi_bridge_enable
is called to enable HDMI. For rxsense is flase, bridge is not
powered up.
When repo_hpd_event is called, we think HDMI connection is stable,
updating rxsense is reliable.

On rockchip platform, hdmi input format is YCbCr444 when output mode
is YCbCr422. Then the value of HDMI_TX_INVID0 on YCbCr422 is same as
the value of YCbCr444, both is 0x09/0x0b. This make enc_out_bus_format
stroed in struct hdmi_data is wrong, which is MEDIA_BUS_FMT_YUV8_1X24
or MEDIA_BUS_FMT_YUV10_1X30.
When android set enc_out_bus_format to YCbCr422, dw_hdmi_setup will be
called and logo will flash.
This patch use colorspace restored in HDMI_FC_AVICONF0 to distinguish them.

-> kernel start(unplug HDMI)
->drm driver probe(plug HDMI)enable crtc(set dclk to 27Mhz)
->VOP timing register is frame effect
->VOP working at 4k output but dclk is 27M
-> VOP frame time 16.6ms * 574 / 27 = 354ms
