If logo display enabled, the rockchip_tve_encoder_loader_protect()
helps to set the tve enable/disable status and call
pm_runtime_get_sync()/pm_runtime_put(), which allows for
the continuation of the display state from the U-Boot stage.
In addition, fix the check of tve mode setting in .mode_set()
to avoid display flashing, which caused by the off/on switch of dac.

It doesn't make sense to always enable tve/vdac clks in probing.
The clks dynamic switching can also help to reduce the power
consumption.

During system suspend and resume, the iddig control
registers maybe changed unexpectedly because of some
reasons, such as grf lost power or modified in phy
tuning, it will cause otg host mode invalid after
system resume if the otg port was forced to host mode
by iddig registers before enter suspend.
This patch check the otg port mode and iddig status
in resume, if the otg port in force host mode and the
iddig status has changed during resume, it recovery
the iddig control regs for host mode.

The current arm32 architecture does not yet support the
HAVE_LD_DEAD_CODE_DATA_ELIMINATION feature. arm32 is widely used in
embedded scenarios, and enabling this feature would be beneficial for
reducing the size of the kernel image.
In order to make this work, we keep the necessary tables by annotating
them with KEEP, also it requires further changes to linker script to KEEP
some tables and wildcard compiler generated sections into the right place.
When using ld.lld for linking, KEEP is not recognized within the OVERLAY
command, and Ard proposed a concise method to solve this problem.
It boots normally with defconfig, vexpress_defconfig and tinyconfig.
The size comparison of zImage is as follows:
defconfig vexpress_defconfig tinyconfig
5137712 5138024 424192 no dce
5032560 4997824 298384 dce
2.0% 2.7% 29.7% shrink
When using smaller config file, there is a significant reduction in the
size of the zImage.
We also tested this patch on a commercially available single-board
computer, and the comparison is as follows:
a15eb_config
2161384 no dce
2092240 dce
3.2% shrink
The zImage size has been reduced by approximately 3.2%, which is 70KB on
2.1M.

(cherry picked from commit ed0f941022515ff40473ea5335769a5dc2524a3f)
1. Fix the csc matrix. For YUV709L to YUV709L, YUV601L to
YUV601L, YUV2020L to YUV2020L, The csc matrix should be
identity matrix. For YUV601L to YUV709L, modeify the csc
matrix.
2. optimize the final calculation result. Use the new r2y
and y2r matrix for csc yuv2yuv and rgb2rgb case. A simple
round is used for csc yuv2yuv and rgb2rgb case for a more
precise result.
