BT1120 dec clk is a 4-bit integer division, which is inaccurate in
most resolutions.
For example, In bt1120->HDMI 1024x768@60Hz scenario, the actual
required clk frequency is 65MHz, while the CPLL frequency is 1188MHz.
After frequency division, the obtained frequency is 62.5MHz, which
deviates too much from the actual clk and causes the screen to be
unable to display.
So if the frequency division is not accurate, apply for a fault
tolerance of up 2% in frequency setting, so that the obtained
frequency is slightly higher than the actual required clk, so that
the deviation between the actual clk and the required clk frequency
is not significant.

The dclk_delayline is to adjust the phase between dclk
and data for bt1120/bt656/rgb interface.
According to the rk3576 SI test report, the dclk_delayline
should be 0x5 in order to improve signal quality.

According to ANDROID commit a9567a35d0 ("ANDROID: arm64: Disable workaround
for CPU errata 2441007 and 2441009"):
CPU errata 2441007 (Cortex-A55) and 2441009 (Cortex-A510) are categorised
as "rare" by Arm and consequently the workaround is not intended to be
deployed in practice as the issue is not expected to occur in real-world
environments.
Given that the cost of the workaround, which issues additional broadcast
TLB invalidation requests, has been shown to impact kswapd significantly
on Pixel devices, disable the workaround following Arm's recommendation.

Put "component_add" in the attach call so that dsi host and dsi device
(panel or bridge) can be regarded as a component as a whole.
dsi calls "mipi_dsi_host_register" so that the panel executes the probe
process or the bridge successfully executes "mipi_dsi_device_register_full"
during the probe process. The panel or bridge triggers "component_add"
by calling mipi_dsi_attach after the probe is successful.
Through the above modifications, you can avoid dsi defer probe infinitely
due to panel configuration errors.
