ANDROID: GKI: regulator: core: allow long device tree supply regulator property names

Browse Source 
The length 32 buffer in of_get_regulator() limits the maximum
possible supply name to 24 characters (32 - 1 [null terminator]
- 7 [strlen("-supply")]).  This causes problems for device
nodes with longer supply property names.

Increase the size of the buffer to remove this artificial
restriction.
