Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different
hardware settings) calls devm_kfree() and then devm_kzalloc() to
reallocate color module data structure. But this reallocation cannnot
guarantee the new address is unchanged, but the caller will use the
old address, which is wrong.
Fix it by separate color module from general components, this patch
separate color module to independent files, like mtk_disp_ovl.c and
mtk_disp_rdma.c do

There are some hardware settings changed, between MT8173 & MT2701:
DISP_OVL address offset changed, color format definition changed.
DISP_RDMA fifo size changed.
DISP_COLOR offset changed.
MIPI_TX pll setting changed.
And add prefix for mtk_ddp_main & mtk_ddp_ext & mutex_mod.

If we want to set the hardware OD to relay mode,
we have to set DISP_OD_CFG register rather than
OD_RELAYMODE; otherwise, the system will access
the wrong address.

Some panels only accept bpc (bit per color) 6-bit.
But, the default bpc in mt8173 display data path is 8-bit.
If we didn't enable dithering function to convert bpc,
display cannot show the smooth grayscale image.
In mt8173, the dithering function in OD (OverDrive) and
GAMMA module, we have to config them with
connector->display_mode.bpc when CRTC initial.
1. Clear the default value at *_DITHER_5 and *_DITHER_7 register.
2. Calculate the LSB_ERR_SHIFT bits and ADD_LSHIFT bits two values.
i.e. Input bpc of OD is 10 bits, we assume the bpc of panel is 6-bit,
so, we need to set 4-bit to LSB_ERR_SHIFT and ADD_LSHIFT bits respectively.
3. Then, set the OD or GAMMA to dithering mode depends on path-1 or path-2.

In order to correct brightness values, we have
to support gamma funciton on MT8173. In MT8173,
we have two engines for supporting gamma function:
AAL and GAMMA. This patch add some GAMMA engine
basic function, include config, start and stop
function.

This patch adds an initial DRM driver for the Mediatek MT8173 DISP
subsystem. It currently supports two fixed output streams from the
OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
