SM8350 and SM8450 use 5nm DSI PHYs, which share register definitions
with 7nm DSI PHYs. Rather than duplicating the driver, handle 5nm
variants inside the common 5+7nm driver.

Quirk is quite an unfortunate name considering what we use it for.. but I

suppose it can stay, as otherwise even more renaming would have to be done.

msm-5.10 has it as 0x3d : 0x00 for both v4.2 and v4.3 in DPHY mode

Either thunderbird is acting up (again) or the code after the first 
comment is

indented with spaces instead of tabs.

> msm-5.10 has it as 0x3d : 0x00 for both v4.2 and v4.3 in DPHY mode

Checking with the latest display-drivers sources at [1]:

There is a common code block using 0x3c : 0x00, but after that at line 
398 comes the special case for >= 4.3, which sets 0x3d : 0x01;


[1] 
https://git.codelinaro.org/clo/la/platform/vendor/opensource/display-drivers/-/blob/DISPLAY.LA.2.0.r1-08400-WAIPIO.0/msm/dsi/dsi_phy_hw_v4_0.c#L378

This big if/switch is a little bit excessive, but I thought it might be 
easier to review it this way. I might still merge some of the clauses.

Would you find the following code part cleaner to review/compare?
