Existing Tegra DSI driver mostly fits T114 apart MIPI calibration
which on T114 has dedicated driver. To resolve this MIPI calibration
logic was split for pre-T114 and T114+ devices.

If DISP1 is a PLLD/D2 child, it cannot go over 370MHz. The cause
of this is not quite clear. This can be overcomed by further
halving the PLLD/D2 if the target parent rate is over 800MHz.
This way DISP1 and DSI clocks will have the same frequency. The
shift divider in this case has to be calculated from the
original PLLD/D2 frequency and is passed from the DSI driver.

With the commit 4fcba5d556b4 ("regulator: implement basic reference
counter") the return value of regulator_set_enable may be EALREADY or
EBUSY for fixed/gpio regulators and may be further expanded on all
regulators.
Change to use the more relaxed regulator_set_enable_if_allowed to
continue if regulator already was enabled or disabled.

Adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features
like ganged mode won't work. Driver is heavily based on
mainline Tegra DSI and re-uses much of its features.
Only T30 is supported for now but T20 support can be added
if any supported devices will be found.
Driver is wrapped as panel driver since Tegra DC driver supports
only panel drivers calls.
