Subject: [PATCH v2] media: dt-bindings: Correct camss VDDA PLL supply
 description

From: David Heidelberg <david@...t.cz>

Usually, the supply is around 1.2 V, not 1.8 V. Rather remove mention of
voltage from the description.

Fixes: 849139d46d09 ("media: dt-bindings: media: camss: Fixup vdda regulator descriptions sdm845")
Signed-off-by: David Heidelberg <david@...t.cz>
---
Added only Fixes tag for the initial commit, not all the copy-paste
propagated ones.
---
Changes in v2:
- Applied suggestion to clarify the description. (Krzysztof)
- Link to v1: https://lore.kernel.org/r/20251212-docs-camss-fixes-v1-1-5c011505ff59@ixit.cz
