Each phy version is tightly coupled with the corresponding PLL code,
there is no need to keep them separate. Fuse source files together in
order to simplify DSI code.

The PLL_LOCKDET_RATE_1 was being programmed with a hardcoded value
directly, but the same value was also being specified in the
dsi_pll_regs struct pll_lockdet_rate variable: let's use it!
Based on 362cadf34b9f ("drm/msm/dsi_pll_10nm: Fix variable usage for
pll_lockdet_rate")

The number of fractional registers bits is known and already set in
the frac_bits variable of the dsi_pll_config struct here in 7nm:
remove the TODO by simply using that variable. This is a copy of
196145eb1af1 ("drm/msm/dsi_pll_10nm: Solve TODO for multiplier frac_bits
assignment").

Fix setting min/max DSI PLL rate for the V4.1 7nm DSI PLL (used on
sm8250). Current code checks for pll->type before it is set (as it is
set in the msm_dsi_pll_init() after calling device-specific functions.

PHY disable/enable resets PLL registers to default values. Thus in
addition to restoring several registers we also need to restore VCO rate
settings.

Neither of these code-paths apply to older 32b devices, but it is rude
to introduce warnings.

This adds support for the 7nm ("V4") DSI PHY/PLL for sm8150 and sm8250.
Implementation is based on 10nm driver, but updated based on the downstream
7nm driver.
