UPSTREAM: doc: Fix statements on case sensitivity for regulator prefix 

The regulator bindings state that regulator prefixes are allowd to be
in upper or lower case. However pmic_bind_children from pmic_uclass uses
strncmp to compare DT node name against prefix. This comparison is case
sensitive hence the regulator driver prefix case matters.

For the node name e.g.: "prefix[:alpha:]num { ... }":
- the driver prefix should be: "prefix" or "PREFIX" - case insensitive
- the driver prefix should be: "prefix" - case sensitive
- the node name's "num" is set as "dev->driver_data" on bind
Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "LDO1", "LDOREG@1"...
Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "ldoreg@1, ...
Optional properties:
- regulator-name: a string, required by the regulator uclass
