Subject: [PATCH v2 02/15] dt-bindings: pinctrl: stm32: use strings for enum property 'st,package'

The property 'st,package' reports the SoC package used in the
board DT and is used to inform the driver about which pins are
available for use by the pinctrl driver.
It has historically been declared as an uint32 enum, where each
value is a power of 2.

Deprecate the use of the numeric value and replace it with more
readable string values.
