[PATCH V3 1/1] input: gpio-keys: add support for disable button from DT

[Laxman Dewangan <ldewangan@nvidia.com>]

Add support to disable the button from DT via status property
if given button is not supporting on given platforms.

This will help to re-use the existing dtsi file with status
enable/disable across platforms.

Changes from V1: 
- Converted print to dev_dbg.
Changes from V2:
